Lions running back Kevin Smith will be a game-time decision for the team's contest against the Bears on Sunday.
Smith had 101 yards on 16 carries when he left last week's win over the Redskins with a shoulder injury.
"Um, it remains to be seen," coach Jim Schwartz told the Detroit Free-Press. "There's a big difference in non-padded practices on Thursday and Friday and an NFL football game. Still got a long way to go. We'll know a little bit more tomorrow, maybe a little bit more Sunday morning."
