The 49ers released their most skimpy injury report of the season on Saturday.
The club ruled out nickel back K'Waun Williams due to a high-ankle sprain. And cornerback Emmanuel Moseley is listed as questionable with a hamstring injury.
Moseley only took part in limited practices throughout the week after the club moved to Glendale, Arizona, their home for as long as Santa Clara County bans contact sports teams from practicing and playing due to the spread of COVID-19.
Moseley has started eight of the nine games in which he has appeared this season. Jason Verrett and Richard Sherman are scheduled to make their second starts together on Monday against the Buffalo Bills.
Moseley is in line to take over as the team's nickel back in place of Williams and Jamar Taylor, who sustained a season-ending torn ACL in the 49ers' 23-20 victory over the Los Angeles Rams in Week 12.
It is unclear who will play nickel back if Moseley is unavailable. Verrett and Dontae Johnson could be options to cover the slot receiver in Robert Saleh's defense.
The 49ers are expecting to be full strength at the running back and wide receiver positions. Raheem Mostert, Tevin Coleman, Jeff Wilson and Jerick McKinnon could see action at running back, while Deebo Samuel, Brandon Aiyuk, Kendrick Bourne and Richie James will play the receiver spots.
Here are the complete injury reports for both teams:

Questionable: CB Emmanuel Moseley (hamstring)
