Own the next man up before the starter goes down.

Acquired from Pittsburgh for a 2028 sixth-rounder at cutdowns after a 2.5-yards-per-carry rookie year. Played zero offensive snaps in Week 1 despite the coaching staff suggesting all three backs would be involved, leaving him without a defined role and third in a three-man room.

Injury history: No significant reported injury absences. His lack of usage in 2025 and in Week 1 of 2026 reflects role and performance, not health.

Pure home-run speed threat brought in as a change-of-pace weapon and now in a tight RB2 race with Vidal. Explosive in space but slight, with a major knee injury behind him — not a candidate to carry a full workload.

Injury history: Career has been shaped by a torn ACL suffered in December 2023 that cost him most of 2024; usage stayed limited through 2025 as he worked back. Healthy in 2026 camp after signing with the Chargers.

Among the NFL's best all-around fullbacks — elite lead blocker, sure-handed on check-downs and a core special-teamer. Occasional short-yardage carries only; not a factor in the RB pecking order.

Injury history: Durable across the last three seasons with no long injury absence; one of the more available fullbacks in the league.

Passing-down specialist and core special-teamer who is listed ahead of Davis but profiles as a receiving back, not a runner. Buffalo would not hand him 15 carries a game if Cook went down.

Injury history: Veteran with no long injury absence in the last three seasons; used in a limited, specialized role that keeps his workload low.

Signed from the practice squad to the 53-man roster Sept. 15 as the corresponding move for Sampson's IR placement. Experienced small-bodied change-of-pace back from four seasons in Denver; adds a passing-down option behind Judkins but has not been reported as a designated backup.

Injury history: No verified injury information gathered this cycle. Missing injury data does not establish health.

Veteran lead blocker and special-teams contributor. Sampson's IR placement reshuffled the running back room but does not change Burton's job; he takes a handful of short-yardage or goal-line carries at most and is outside the backfield pecking order.

Injury history: Long-tenured fullback, age 34, with no significant injury absences reported in the last three seasons. No new injury reported this cycle.

Physical third-year back set to reclaim the No. 2/No. 3 role and a real part of the committee. His own August groin issue and Allen's better passing-down profile keep him a rotational piece rather than the takeover option.

Injury history: 2025: missed the season finale. 2026: dealt with a groin issue through August alongside Hall, though he was listed as a full participant on the estimated report entering Week 1.

Elite kickoff returner and special-teams weapon who re-signed for that role. Very little offensive usage; not part of the plan at running back if Hall missed time.

Injury history: Healthy through the 2026 summer — one of two Jets backs who avoided injury entirely; described as day-to-day at points but no significant absence.

Now the only backup taking offensive snaps: 11 snaps (17%) in Week 2, nine of them on pass plays, with one catch for 13 yards and one carry for 7. Used mainly as a pass-down blocker/outlet rather than a runner, so he is a partial, not full, beneficiary if Gibbs missed time.

Injury history: 2026: missed most of training camp and all of preseason with a broken nose and an eye injury; healthy and active in Weeks 1-2. Converted safety with limited offensive exposure in 2024-2025 and no prior long absence.

Fringe-roster third back and special-teams body. No meaningful offensive role; Houston would look outside the building before giving him carries.

Injury history: Has spent most of his career on practice squads and reserve lists with assorted injuries; no significant NFL regular-season sample.

Second-year back with the most complete backup skill set in the room, but he was passed for the No. 2 job by rookie Seth McGowan and is now RB3. Questionable for Week 2 with a knee issue that surfaced Thursday. Still the most plausible lead back if Taylor missed extended time, though the demotion weakens that case.

Injury history: No significant reported injury absences since entering the league in 2025; his light usage (26 career touches) reflects Taylor's workload, not health. 2026 Week 2: added to the injury report Thursday with a knee issue and did not practice that day, then listed questionable vs. Kansas City (reports dated 9/17 and 9/18). No return timetable stated beyond the game designation.

Compact early-down back listed as RB3 who moves up in the Week 1 rotation with Henderson out. Depth insurance rather than a genuine next-man-up option.

Injury history: No significant reported injury absences; minimal NFL regular-season sample.

Veteran fullback and special-teams captain type used as a lead blocker. Not a ball carrier.

Injury history: Durable in a small role over the last three seasons with no long absence.

Jacksonville's top option on all passing downs in camp and a polished protector, but built as a specialist rather than a volume runner. His Week 1 availability is in doubt with a soft-tissue issue.

Injury history: 2026: unspecified soft-tissue injury late in camp; Liam Coen said he would be 'pleasantly surprised' if Allen were ready for Week 1. No prior long absence.

33-year-old veteran kept for third-down reliability and special teams, especially with Allen banged up. Trustworthy in protection; no longer a candidate for meaningful carries.

Injury history: Durable in a small role over the last three seasons with no long absence, but he is 33 and has never carried a heavy workload.

Material change: despite preseason flashes, Smith played just three snaps in Week 1, all on special teams, with the rookie Johnson ahead of him. Reporting in September described him as a gadget back lacking the size to be trusted in pass protection. Deep-bench only unless two backs ahead of him are unavailable.

Injury history: No reported injury absences since entering the league in 2025. He has played little, so the clean record is weak evidence either way.

Fourth-year converted linebacker signed to Kansas City's initial 16-man practice squad on Sept. 1, 2026 - a notable add given Andy Reid's long use of fullbacks. Blocking and special-teams role only; he carries no meaningful carry or handcuff value.

Injury history: No injury history researched for this profile; the absence of reports does not establish health.

Explosive, straight-line third-year back who won the No. 2 job. Similar speed archetype to Achane and would get the first crack at carries if he sat, but Miami would likely rotate him with Gordon rather than hand him a 20-touch role.

Injury history: Has dealt with assorted lower-body issues that limited his availability across 2024-2025 without a single long absence; healthy entering 2026 as the RB2.

Rookie fullback and special-teams body. No role in the backfield rotation.

Injury history: Rookie with no NFL injury history.

Veteran passing-down back and trusted blocker, valuable to the Bengals for protection and check-downs. At 30 he is not a 15-carry answer; Cincinnati would be in trouble on early downs if Brown missed extended time.

Injury history: Durable veteran with no long injury absence in the last three seasons, though at 30 he has been used in a small, specialized role.

Undrafted rookie rounding out the depth chart behind Warren and Dowdle. Special-teams body with no projected offensive role.

Injury history: Rookie with no NFL injury history.

Rookie fullback used as a blocker in heavy packages and on special teams. No role in the running back rotation.

Injury history: Rookie with no NFL injury history.

Seattle's passing-down back: he took all 10 of the team's third-down snaps in Week 1 plus two short-yardage snaps, with five carries and the only other RB target. Pre-season reporting flagged him for a 'heavy dose' of work on third down for his receiving and pass protection. Holds real standalone value beside Price.

Injury history: No significant reported injury absences since entering the league in 2024; healthy through 2026 camp and played Week 1.

Fullback/H-back kept for blocking and special teams. Not a ball carrier and not part of the backfield rotation.

Injury history: No significant reported injury absences in the last three seasons; used almost exclusively as a blocker and on special teams.

Physical rookie sharing the No. 3 spot who fits Washington's stated situational approach on early downs and in short yardage. Real ability, but he would split work rather than take over if Croskey-Merritt sat.

Injury history: Rookie with no NFL injury history; healthy through camp and the preseason.

Quick change-of-pace and passing-down complement who would normally absorb receiving work if Pollard sat, except he is nursing his own ankle and also missed practice Wed., Sept. 23. Both top backs being limited in the same week is the material change. Availability, not ability, remains the central risk with Spears.

Injury history: Ankle: did not practice Wed., Sept. 23 (Titans report), the same week as Pollard; no return timetable stated. Listed Questionable. Sept. 23 fantasy item (date-only) framed both ankles as soreness rather than a multi-week issue. History: repeated 2024-25 misses (ankle, hamstring, concussion) plus a long-known knee condition dating to college; no season-ending injury, but rarely a clean slate.

Big-bodied short-yardage and special-teams back. With Pollard and Spears both ankle-limited as of Sept. 23 he is the healthy veteran body in a thinned room, but Sept. 23 coverage pointed to rookie Nicholas Singleton, not Chestnut, as the workload beneficiary. Depth piece rather than a next-man-up hold.

Injury history: Not listed on the Titans' Wednesday, Sept. 23 injury report and no significant reported absences in recent seasons. Absence from a report does not by itself confirm full health.

Material change: Harris was a healthy scratch for Week 1 (Sept. 13) as the Giants dressed Skattebo, Tracy and Singletary. His track record of 250-plus-carry seasons still makes him the most proven lead back in the room, but he is currently fourth in line and must earn his way back into the rotation. Not a usable redraft hold yet.

Injury history: Never missed a game in his first four seasons, then tore his Achilles in Week 3 of 2025, ending that season. Signed with the Giants in mid-August 2026 and has practiced without restriction. Week 1 inactive was a coach's decision, not an injury designation.

Still the most complete backup - runs, catches and protects - but his grip slipped in August after a missed blitz pickup in the preseason opener and a fumble near the goal line against Miami, dropping him into a three-way RB2 tie with Harris and Singletary. Active Week 1. Remains the likeliest Skattebo replacement, but no longer clearly.

Injury history: Scattered missed games in 2024-2025 (including a shoulder issue) but no long absence. Healthy through 2026 camp and active for Week 1 on Sept. 13; no injury designation reported.

Now one of only three running backs on Arizona's 53-man roster alongside Love and Allgeier, with Conner on IR. That raises his emergency floor but not his projected role: he is a kickoff returner and depth back, not a player the run game would be built around.

Injury history: No significant reported injury absences 2023-2025; snaps have come mostly on special teams and in reserve duty. No new injury reported this cycle - absence of injury data does not establish health.

Second-year back who lost the No. 2 job to third-round rookie Kaelon Black, who Shanahan said earned it in training camp while James was slowed by a camp rib injury. Healthy for Week 2 and the next man up if Black's groin sits him, but as RB3 his handcuff case is weaker than it was a month ago.

Injury history: No significant reported injury absences since entering the league in 2025; missed 2026 training camp time with a rib injury. Carries no designation on San Francisco's Week 2 injury report (dated 9/18).

The league's signature fullback and the linchpin of Shanahan's blocking and play-action schemes, still a real receiving threat. Practicing fully in Week 2 despite a finger issue. Takes a handful of touches a year and is not a backfield contingency at any point.

Injury history: Remarkably durable for the position with no long injury absence in the last three seasons. Listed with a finger injury on San Francisco's Week 2 report (dated 9/18): limited Thursday, full Friday, no game designation. He is 35 and in his 14th season.

Rookie who moves up the depth chart with Mason on IR, but Minnesota signed DeeJay Dallas off the practice squad and added Jerome Ford as further depth rather than handing him the complementary role. Quick, undersized change-of-pace type; a committee piece at most if Jones were also unavailable.

Injury history: Rookie with no NFL injury history reported. Absence of injury data does not establish health.

Rookie fullback/H-back used as a blocker and special-teamer. Mason's IR placement reshaped the running back rotation but has no bearing on his role.

Injury history: Rookie with no NFL injury history reported. Absence of injury data does not establish health.

Speedy RB3 who offers a different archetype from Irving and Gainwell and has flashed in spot duty. A committee piece if either back above him missed time, not a lead-back solution.

Injury history: No significant reported injury absences over the last three seasons; usage limited by depth-chart position.

Third back and Baltimore's primary kickoff returner. Would get late-game carries or spell Henry for a series, but the coaching staff has pointed to Hill, not Ali, as the man who absorbs work if Henry sits.

Injury history: Missed time as a rookie in 2024 and spent stretches on the sideline in 2025; no chronic issue reported. Enters 2026 healthy as the third active back.

Lead-blocking fullback and special-teams core player who occasionally gets a short-yardage touch. Not part of the running back rotation in any meaningful way.

Injury history: No significant reported injury absences in the last three seasons.

2024 sixth-rounder whose value is on special teams: a 25.9-yard kick-return average and 855 return yards in 2025, 10th in the league. Third in the pecking order with minimal offensive usage. If Jeanty missed time the work would go primarily to Mike Washington Jr., leaving Laube a complementary piece.

Injury history: No 2026 injury designation reported through Week 2 and no significant injury history located in the sources reviewed; he was available for return duty throughout 2025. Missing injury data is not evidence of durability.

H-back/fullback signed after four seasons in Pittsburgh and listed FB1 on the Week 1 depth chart. Brings blocking, receiving and special-teams value with five career scrimmage touchdowns. Las Vegas values his versatility, but he is not a candidate for meaningful carries behind Jeanty.

Injury history: No 2026 injury designation reported through Week 2. No significant injury history surfaced in the sources reviewed, which is not the same as a verified clean record — his Pittsburgh-era availability was not checked in this pass.

Material downgrade. Miller was a healthy scratch in Week 2 - not hurt - as Alvin Kamara returned from injury and undrafted rookie CJ Donaldson held his spot on tailback, fullback and special-teams value. Behind Travis Etienne, Kamara and Donaldson he has no standalone or handcuff value in redraft. Contract year, and beat reporting floats him as a trade candidate if this holds.

Injury history: Availability has defined his career, with multiple injury-shortened seasons since 2023. Correction for 2026: his Week 2 inactive status vs Baltimore (Sept 20, date-only) was reported as a healthy scratch, not an injury - no injury designation was attached. Week 1: 9 carries for 30 yards and a TD.

Elevated from the practice squad for Week 1 at Detroit as part of the roster shuffle around Estime's IR placement, and now carried on the active roster. No reported role in the offensive rotation yet; a body added behind Etienne, Kamara and Miller rather than a defined committee piece.

Injury history: No verified injury information gathered this cycle. Missing injury data does not establish health.

Fourth-round rookie and Denver's RB3, a compact early-down runner. His debut was a non-factor: three offensive snaps and no touches at Kansas City in Week 1. With Harvey questionable he could see a first real workload, but Payton's passing-down role belongs to Harvey and Coleman is still unproven as a pro.

Injury history: Rookie with no NFL injury history; healthy through his first training camp and active for Week 1. Not listed on Denver's Week 2 injury report (dated 9/18).

Small, quick fourth back who has mostly been practice-squad depth. Emergency option only in a room where Harvey and Coleman are ahead of him.

Injury history: No significant reported injury absences in the last three seasons; has spent most of his career as a roster-bubble depth back.

Change-of-pace third back and special-teams contributor who was the designated spell option behind Barkley until ribs knocked him out of the opener. The Bigsby trade had already pushed him down the pecking order.

Injury history: 2026: suffered a rib injury just before halftime of the season opener against Dallas and did not return, after picking up 26 yards on three carries. Otherwise a quiet, mostly available first two seasons.

Short-yardage and goal-line specialist and a reliable pass protector, which keeps him on the roster. Limited as a between-the-tackles volume runner; Chicago would turn to Monangai, not Johnson, for the lead role.

Injury history: Has missed games in multiple seasons since 2023 with concussion and assorted issues; no single long absence in the last three years but rarely a full slate.
