Vaki (thumb) is questionable for Sunday's matchup against the Rams, Eric Woodyard of ESPN.com reports.

Vaki was limited in practice throughout the week with a thumb injury he suffered in Week 13 against the Packers. Given that he played through the injury in Week 14, the 24-year-old should have a good chance to play Sunday against the Rams, barring a setback. Should he sit out, Jacob Saylors will serve as the No. 3 running back behind Jahmyr Gibbs and David Montgomery.

McCaffrey (illness) doesn't have an injury designation for Sunday's game against the Titans, Cam Inman of The San Jose Mercury News reports.

The 49ers added him to the injury report mid-week due to an illness, but McCaffrey still managed a limited practice Thursday and full session Friday. He should be fine for his usual role this Sunday against the Titans, albeit with higher-than-usual risk of being pulled early from a blowout. Of course, that might be the same scenario in which McCaffrey puts up a ton of points early in the game.

Marks (knee) doesn't carry an injury designation for Sunday's game against the Cardinals after practicing fully Friday.

Marks sat out the Texans' first practice of the week Wednesday, but he upgraded to limited participation Thursday before taking every rep Friday. He'll be ready to play this weekend and could even end up taking on a larger share of the work out of the backfield if Nick Chubb (ribs) -- who is listed as questionable -- is out Sunday or available only in a limited capacity. After Chubb played just eight snaps before exiting the Texans' Week 14 win over the Chiefs, Marks went on to record a season-high 26 carries for 68 yards while adding two receptions (on three targets) for eight yards and a touchdown.

Achane (ribs) was a limited participant in Friday's practice, Marcel Louis-Jacques of ESPN.com reports.

Achane wore a red non-contact jersey at practice Friday, Joe Schad of The Palm Beach Post reports, but he appeared to be running at full speed without signs of discomfort. Per Hal Habib of The Palm Beach Post, the standout running back is testing forms of protective equipment he could use to guard his ribs during Monday's road matchup against the Steelers, while Barry Jackson of the Miami Herald reports that the Dolphins do expect Achane to be available Week 15. That said, after the impressive showing Jaylen Wright logged Week 14, Miami could opt to assign Achane less touches than his workhorse role usually entails, even if he's active. He'll have one final chance to handle contact reps at Saturday's practice.

Jacobs (knee) is listed as questionable for Sunday's game against the Broncos.

It's the same knee injury that held Jacobs out for Week 12, with reports suggesting he was bothered by increased swelling in the aftermath of a Week 14 win over Chicago. He didn't practice Wednesday or Thursday but returned to limited participation Friday, setting up a potential game-day decision ahead of a 4:25 p.m. ET kickoff Sunday. Fellow Packers running back Emanuel Wilson becomes an attractive lineup option if Jacobs ends up inactive, having taken 28 carries for 107 yards and two TDs when Jacobs missed the Week 12 win over Minnesota.

Chubb (ribs) is listed as questionable for Sunday's game against the Cardinals.

Chubb missed back-to-back practices to begin Week 15 prep, but he returned as a limited participant Friday. If Chubb is able to gain clearance in time for Sunday's matchup, he'll stand to handle the No. 2 backfield role behind Woody Marks. If Chubb is unable to face Arizona, however, Dare Ogunbowale will figure to inherit an increased workload behind Marks.

Hall (knee) doesn't have a designation for Sunday's game in Jacksonville, Rich Cimini of ESPN.com reports.

Hall kicked off this week with no practice Wednesday due to a knee injury, but he progressed from limited Thursday to all activity Friday, clearing him to continue to lead the Jets backfield this weekend. Since the team's Week 9 bye, he's racked up 93 touches for 427 yards from scrimmage and two total TDs over the last five contests. With undrafted rookie QB Brady Cook set to start Sunday with Tyrod Taylor (groin) and Justin Fields (knee) unavailable, Hall could take on even more of the onus for New York's offense.

Demercado (ankle) is listed as questionable for Sunday's game at Houston, Tyler Drake of ArizonaSports.com reports.

Demercado still hasn't logged a full practice since suffering a high-ankle sprain, but he's at least managed limited sessions for two weeks now, showing enough to be listed as 'questionable' after the past three weeks saw him ruled out Friday. Once he returns, Demercado figures to push Bam Knight and/or Michael Carter for playing time.

Rodriguez (groin) is listed as questionable for Sunday's game at the Giants.

The Commanders listed Rodriguez as a limited participant Thursday and Friday, after holding him out from Wednesday's session. Jacory Croskey-Merritt and Jeremy McNichols will take on larger roles if Rodriguez is declared inactive before the 1:00 p.m. ET kickoff Sunday.

McCaffrey (illness) is practicing Friday, Noah Furtado of the San Francisco Chronicle reports.

The illness apparently isn't serious, considering McCaffrey was a limited practice participant Thursday and is now practicing again Friday. He's on track to play Sunday against the Titans.
