Kamara (groin) is doubtful for Sunday's game at Tampa Bay, Jeff Nowak of WWL Louisiana reports.

Kamara didn't practice this week, but coach Darren Rizzi said the running back will go through a workout Saturday morning to give him once last chance to prove he's healthy enough to play. Kamara mentioned wanting to play earlier this week, and he's just 50 yards away from the first 1,000-yard rushing season of his career. As much as he'd like to play, it sounds like his injury situation isn't cooperating.

Mattison is expected to be the Raiders' starting running back Sunday versus the Chargers with Ameer Abdullah (foot) listed as doubtful for that contest, Tashan Reed of The Athletic reports.

Among his 13 appearances this season, Mattison has surpassed 4.0 YPC just one time (5-60-0 back in Week 4 against the Browns), and overall he's averaged 3.2 yards on his 126 rushes to date. He at least has supplemented poor performance on the ground with 32 catches (on 43 targets) for 283 yards while also scoring five total TDs. With Abdullah likely sidelined this weekend, Mattison should take on an expanded role, but he also may yield RB reps to Chris Collier and maybe even Dylan Laube.

Kamara (groin) doesn't appear to be practicing Friday, Mike Triplett of NewOrleans.Football reports.

Kamara reportedly wants to play and is just 50 yards away from his first 1,000-yard rushing season, but it seems his groin isn't cooperating and he'll likely miss another game. Kendre Miller (concussion) was also missing from the start of Friday's practice, likely leaving the Saints backfield in the hands of Jamaal Williams, Clyde Edwards-Helaire and Jordan Mims for Sunday's season finale against Tampa Bay.

Jones (quadriceps) doesn't have an injury designation for Sunday's game at Detroit.

He sat out the fourth quarter of last week's win over Green Bay but was never likely to miss the upcoming game due to a quad bruise. With the NFC North and a first-round bye on the line this weekend, Jones may even take a larger share of the RB workload than he normally does.

Homer (hamstring) has been ruled out for Sunday's game against the Packers.

Homer hasn't played since Week 15 and will finish the season with six carries for 23 yards and three catches for 11 yards on offense. As a special teams contributor, Homer logged six tackles (three solo) and returned one kickoff for 29 yards. His two-year, $4 million deal is scheduled to expire in March, and Homer is slated to hit free agency as a 26-year-old.

Williams will be held out of Sunday's game against the Seahawks, Adam Grosbard of The Orange County Register reports.

Coach Sean McVay confirmed Friday that Williams and WRs Puka Nacua and Cooper Kupp will be among the players rested Week 18, as will QB Matthew Stafford and multiple starting linemen. QB Jimmy Garoppolo, RB Blake Corum and WRs Tutu Atwell and Jordan Whittington may be the focal points of the offense this Sunday.

Coach Antonio Pierce said Friday that Abdullah (foot) will be listed as doubtful for Sunday's game against the Chargers, Paul Gutierrez of ESPN.com reports.

In the wake of a standout 20-carry, 115-yard effort this past Sunday at New Orleans that also included three catches (on four targets) for 32 yards, Abdullah has been tending to a foot injury that didn't allow him to practice this week. He thus appears in line to miss his first game of the campaign, which would allow the combination of Alexander Mattison, Chris Collier and perhaps even Dylan Laube to man the Raiders backfield Sunday.

Spears (concussion) has been ruled out for Sunday's season finale against the Texans, Jim Wyatt of the Titans' official site reports.

While Spears has been ruled out, fellow running back Tony Pollard (ankle) is viewed as a game-time decision for Sunday's 1:00 p.m. ET contest, per Turron Davenport of ESPN.com. In the event that Pollard ends up sidelined as well, however, Julius Chestnut would be in line to see an expanded role Week 18, with Joshua Kelley and possibly practice-squad member Jabari Small mixing in.

The Browns elevated Kibodi from the practice squad for Saturday's game against the Ravens.

With Jerome Ford (ankle) and Pierre Strong (concussion) sent to injured reserve Friday, Kibodi will slot in as the Browns' RB3 behind D'Onta Foreman and John Kelly versus Baltimore. The 26-year-old has yet to appear in a regular-season NFL game.

The Browns placed Strong (concussion) on injured reserve Friday.

D'Onta Foreman and John Kelly will handle backfield duties for Cleveland's Week 18 finale. Strong's 2024 season ends with 26 carries for 108 scoreless yards and a 14-104-0 receiving line on 22 targets as the Browns' third running back for much of the year. The 2022 fourth-round pick is currently under contract for a non-guaranteed salary of $1.1 million next season, the final year of his rookie deal.
