Williams (shoulder/neck) didn't practice Thursday, Jon Machota of The Athletic reports.

Williams hasn't practiced this week due to the shoulder/neck injury that he's been dealing with since a Week 15 matchup with the Vikings. He's still racked up 39 touches for 188 yards and two rushing TDs during that span, while No. 2 RB Malik Davis has turned his 38 touches into 163 total yards and one TD on the ground. Davis (eye/calf) also hasn't practiced this week, so rookie Jaydon Blue is the only healthy player at the position on the active roster.

Vidal (neck) practiced fully Thursday, Eric Smith of the Chargers' official reports.

Meanwhile, Omarion Hampton (ankle) didn't practice Thursday, and Hassan Haskins (concussion) was limited, so at this stage the composition of the Chargers' Week 18 backfield has yet to be determined. In the wake of his full practice, Vidal is on track to be available Sunday against the Broncos, but if the team elects to rest or limit key players apart from QB Justin Herbert (who will give way to Trey Lance this weekend), it's possible that Jaret Patterson and/or Amar Johnson will be elevated from the practice squad and see their share of touches alongside Vidal in Los Angeles' regular-season finale.

Hampton (ankle) didn't practice Thursday, Eric Smith of the Chargers' official site reports.

Hampton also logged a 'DNP' on Wednesday, and considering that the Chargers are planning to rest QB Justin Herbert (hand) in Week 18, it's possible that they'll err on the side of caution with Hampton, with the team's looming playoff run in mind. In any case, Friday's final injury report will reveal whether Hampton has a chance to be in uniform Sunday against the Broncos or instead will have to wait until wild-card weekend to see his next game action.

Corum (ankle) didn't take part in Thursday's practice, Adam Grosbard of The Orange County Register reports.

Corum made an early exit from Monday's loss in Atlanta due to an ankle injury that so far hasn't allowed him to mix into any drills in the meantime. He'll have one more chance to do so, or else he and fellow RB Kyren Williams (ankle, LP so far this week) may enter the weekend with designations for Sunday's game against the Cardinals.

Williams (ankle) practiced in a limited fashion Thursday, Adam Grosbard of The Orange County Register reports.

Both of the Rams' top two running backs are dealing with health concerns at the moment, but Williams at least has been able to log some on-field work, as opposed to Blake Corum (ankle), who was a non-participant Wednesday and Thursday. Ultimately, Friday's injury report will reveal if Williams and/or Corum carry designations ahead of Sunday's contest against the Cardinals.

Mostert (knee/ankle) did not participate in Thursday's practice, Ryan McFadden of ESPN.com reports.

Mostert's absence from Thursday's practice could be a maintenance day, given that the veteran running back was a full participant in Wednesday's session. His participation in Friday's practice will provide clarity on his status heading into Sunday's regular-season finale against the Chiefs.

McCaffrey (back) doesn't have a designation for Saturday's game against the Seahawks, Nick Wagoner of ESPN.com reports.

McCaffrey initially dealt with a back injury in the fourth quarter of this past Sunday's win against the Bears. Per David Lombardi of SFStandard.com, the issue was described as stiffness by the running back himself Tuesday, when he didn't practice, but McCaffrey got back on the practice field Wednesday as a limited participant and now is clear for Week 18. McCaffrey is four catches away from reaching 100 for the third time in his career.

Kamara (knee/ankle) did not practice Thursday.

Kamara appears on track to miss Sunday's regular-season finale against the Falcons, which would constitute his sixth straight missed contest. With Devin Neal (hamstring) having been placed on IR in Week 16, Audric Estime will be positioned to close out the 2025 campaign as New Orleans' backfield leader if Kamara indeed can't play Week 18.

Jacobs (knee/ankle) practiced in a limited capacity Thursday.

Jacobs has been battling lower-body injuries since he sustained a knee injury Week 11 at the Giants. He sat out Week 12 against the Vikings as a result, but he's suited up for each of the last five contests, totaling 73 touches during that span. Jacobs actually ranked third among Packers RBs in offensive snaps (13) behind Chris Brooks (21) and Emanuel Wilson (17) in Week 17, and with the team locked in to the No. 7 seed in the NFC side of the playoffs, Jacobs could find himself inactive Sunday at Minnesota to get him as healthy as possible for the postseason.

Achane (shoulder) did not practice Thursday, David Furones of the South Florida Sun Sentinel reports.

Achane is missing a second consecutive practice due to a shoulder injury, giving him just one more chance to handle on-field reps ahead of Sunday's regular-season finale against the Patriots. If the star playmaker is unable to suit up Week 18, Jaylen Wright will figure to lead Miami's backfield on the road against New England, while Ollie Gordon will also stand to inherit an increased role on offense.
