CHARLOTTE, N.C. -- Panthers running back Stephen Davis did not practice Wednesday because of a strained left quadriceps.
Davis, who ran for a career-best 1,444 yards this season, is questionable for Sunday's NFC championship game against the Philadelphia Eagles.
He wouldn't answer reporters' questions Wednesday.
If Davis can't play Sunday, second-year back DeShaun Foster will start.
Davis was injured on a 64-yard run in the second quarter of the Panthers' win against St. Louis on Saturday. He left the game and did not return.
Foster replaced him and ran for a career-high 95 yards on 21 carries.
