Jacobs (calf) was limited at practice Thursday, Anthony Galaviz of The Fresno Bee reports.

Back-to-back limited listings bode well for Jacobs' chances of being available for this weekend's game against the Chargers. However, the Raiders' top back will probably need to log a full practice Friday in order to avoid approaching Sunday's 4:25 p.m. ET contest minus a Week 13 injury designation.

Snell (knee) was listed as a limited participant on the Steelers' injury report Thursday, per Mike DeFabo of The Athletic.

Snell appears to have picked up a knee issue at some point during practice, as he popped up on the Week 13 injury report for the first time Thursday. The third-string running back also logged a season-high 12 rushes for 62 yards and a touchdown with Jaylen Warren (hamstring) inactive and Najee Harris (abdomen) forced out during Monday's win versus the Colts. While the nature of this injury is still unclear, Snell will have one more practice to return to full participation, or else he could be in jeopardy of missing Sunday's contest versus Atlanta.

Dillon (quadriceps) practiced in a limited fashion Thursday, Matt Schneidman of The Athletic reports.

Both Dillon and Aaron Jones (shin/glute) are operating under caps on their practice reps to begin Week 13 preparations. There's a chance Friday's injury report clears up the situation, and if the status quo remains between the duo Sunday at Chicago, Dillon would be the No. 2 option behind Jones, the starter.

Mostert (knee) remained limited at practice Thursday, David Furones of the South Florida Sun Sentinel reports.

Mostert, who missed the Dolphins' Week 12 win over the Texans, now has logged back-to-back limited sessions and is trending toward a return to action Sunday against the 49ers. The running back presumably will need to practice fully Friday, however, in order to head into the weekend minus an injury designation.

McCaffrey (knee) was working off to the side during the open portion of Thursday's practice, David Lombardi of The Athletic reports.

The extent of McCaffrey's participation in practice won't be known until the 49ers release their second injury report of the week later Thursday, but the running back looks as though he might be able to do more than he did Wednesday. The fact that McCaffrey was seen on a side field rather than with the main group could mean that he winds up going down as a non-participant for the second day in a row, even though he's donning pads and a helmet Thursday. The 49ers seem to be taking extra caution with McCaffrey while he manages what's believed to be a minor knee issue, but head coach Kyle Shanahan suggested Wednesday that he's tentatively planning on having the star tailback available for Sunday's matchup with the Dolphins.

Jones (shin/glute) practiced on a limited basis Thursday, Matt Schneidman of The Athletic reports.

Jones maintained his activity level from one day prior, as did AJ Dillon (quadriceps, limited Thursday). Considering both running backs have been able to log at least individual drills this week, neither player seems in danger of sitting out Sunday in Chicago. Still, the statuses of Jones and Dillon will continue to be monitored, with Friday's injury report potentially clearing up the situation entirely.

Mixon (concussion) was a limited participant in Thursday's practice, Ben Baby of ESPN.com reports.

Mixon's reps were capped in practice for the second day in a row, an indication that he hasn't made any notable progress since Wednesday as he works his way through the NFL's five-step concussion protocol. If Mixon is able to practice in full Friday, he would likely be in good shape to suit up Sunday against the Chiefs, though he would still need to receive clearance for an independent neurologist before getting the green light to suit up. In the event Mixon can't get cleared for the Week 13 matchup, Samaje Perine would be in store for another turn as Cincinnati's lead back after getting 21 touches (17 carries, four receptions) in last Sunday's win over the Titans.

Kamara (undisclosed) wasn't listed on Thursday's injury report.

Kamara's last snap in this past Sunday's loss at San Francisco was a lost fumble at the goal line, which resulted in the running back visiting the sideline tent and continuing to don pads in the waning minutes of the contest. No injury was reported at the time or in its aftermath, and now he's avoided the Saints' initial practice report of Week 13. Kamara thus is in line to remain the team's primary backfield option Monday in Tampa Bay, especially with Mark Ingram (foot, limited Thursday) dealing with a new health concern.

Harris (oblique) didn't practice Thursday, Teresa Varley of the Steelers' official site reports.

Harris, who suffered an oblique injury against the Colts this past Monday, now has missed back-to-back sessions, though a return to practice in any capacity Friday would boost his chances of suiting up Sunday against the Falcons. If Harris ends up out or limited this weekend, though, Jaylen Warren -- a full participant for the second day in a row after being inactive Week 12 -- would be in line for an expanded role versus Atlanta.

Gaskin (shoulder) was not present for the Dolphins' practice Thursday, Daniel Oyefusi of the Miami Herald reports.

Gaskin did not practice for the second day in a row after popping up with a shoulder injury on Wednesday's injury report. The 25-year-old will now have just one more chance to increase his practice activity Week 13, or else he'll likely be sidelined for Sunday's game versus San Francisco. Gaskin has been a healthy scratch most weeks in the Dolphins' crowded running backs room this season, though he saw his highest usage of the year with Raheem Mostert (knee) inactive Week 12. If both backs are unable to play, then Salvon Ahmed would be in line for increased touches versus the 49ers.
