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

Injury history: Rookie with no NFL injury history.

Stock up. With Mason on IR, Jones a Wednesday DNP with a knee issue and Dallas limited with a toe, the Sept. 23 reporting called Claiborne the only fully healthy back on the active roster, and Minnesota's own depth chart now lists him ahead of Dallas. Undersized change-of-pace rookie - a committee piece if Jones sits, not a bell cow, but the actionable healthy add in this room.

Injury history: Rookie with no NFL injury history reported, and described in the Sept. 23 report as the only fully healthy running back on Minnesota's active roster. 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.

Has forced his way into real work: a team-high 37.7% snap share in the Week 3 loss to Buffalo on 8 carries for 52 yards plus his first career receiving TD, and a room-leading 22 routes over two weeks while Hampton fell to 42%. The new ankle (boot, two limited practices) clouds the near term with no timetable given. Explosive but slight - a rotational weapon, not a workhorse.

Injury history: Career shaped by a torn ACL in December 2023 that cost him most of 2024; usage stayed limited through 2025 as he worked back. 2026: hurt his left ankle in a Wednesday practice before Week 4, was seen in a walking boot and logged limited practice Wednesday and Thursday; listed Questionable with no return timetable reported as of Sept. 30. Slight build.

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.

Converted receiver/returner carried at running back. He is on the active roster rather than the practice squad after Seattle elevated him ahead of the Week 3 Commanders game (reported Sept. 23, date-only), but no backfield role has been reported for him - the usage case is returns and special teams. Not a factor in the RB rotation.

Injury history: Career returner and gadget player rather than a true running back. No 2026 injury reported and he is not listed on Seattle's official Week 4 injury report dated Sept. 30; missing injury data does not establish health.

Fullback/H-back kept for blocking and special teams, cleared through a minor chest injury in Week 3 prep. Not a ball carrier and not part of the backfield rotation.

Injury history: No significant reported injury absences in the last three seasons. 2026: a chest injury put him on Seattle's Week 3 injury report - limited Wednesday, full participant Thursday, and no game status assigned for Sept. 27. Used almost exclusively as a blocker and on special teams.

Denver's No. 3 back, moved up a spot by Coleman's Sept. 26 placement on injured reserve. Both backs ahead of him, Dobbins and Harvey, were cleared without a game status for Week 3, and no current-season usage has been reported for Badie himself - so he is an emergency-only option unless a second injury hits the room.

Injury history: No significant reported injury absences in the last three seasons; has spent most of his career as a roster-bubble depth back. Not listed on Denver's Week 3 injury report (dated Sept. 25), though absence from a report is not positive evidence of health.

Blocking fullback, not a ball carrier: through two weeks he played 12% of Denver's offensive snaps and 67% of special-teams snaps. Elevated from the practice squad for a third straight game on Sept. 26, his maximum allotted, so Denver must sign him to the active roster for him to play beyond Week 3. No backfield touches to project.

Injury history: No injury absences reported in the sources reviewed; missing injury data is not evidence of durability. Available for each of Denver's first three games of 2026 via practice-squad elevations.

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.

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.

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.

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.

Listed on Carolina's practice squad as of Sept. 3, 2026, alongside Ahmani Marshall, after going through training camp with the team. No NFL regular-season role and no reported path to touches behind Hubbard, Brooks and Dillon. Too little verified information to assign a role.

Injury history: No injury reporting located for 2026 and no verified NFL injury history. He is a practice-squad player and therefore not carried on team injury reports, so the absence of injury data establishes nothing about his health.

Rookie on the active roster who has carved out a niche: Moore said on Oct. 1 that Donaldson has 'found his specific role,' and he is part of the group that out-carried Etienne 35-30 over the first three-plus games. With Etienne on IR he should see more snaps, but he is behind Kamara and Miller with no established carry share of his own. Deep bench and dynasty stash only.

Injury history: No verified injury information gathered this cycle, and he does not appear on Saints injury reporting reviewed through Oct. 1. Missing injury data does not establish health. No reported NFL absences for this rookie.
