CHARLOTTE, N.C. -- Carolina Panthers leading tackler Thomas Davis is questionable for Sunday's game against Buffalo with a hamstring injury.
The starting weakside linebacker missed his second straight practice Friday with an injury apparently sustained in practice Wednesday.
Kickoff specialist Rhys Lloyd, running back Jonathan Stewart, fullback Brad Hoover and linebacker Na'il Diggs are also questionable, but all practiced in full Friday.
The speedy Davis is off to the best start of his career with 55 tackles, two sacks and an interception. He's spearheaded Carolina's improved play on defense the last two weeks.
Landon Johnson would likely fill in if Davis can't play, with James Anderson also seeing more time.
