Duren is questionable to return Monday against the Grizzlies after having a tooth dislodged in a collision with Memphis' Jaren Jackson in the first quarter, Keith Langlois of the Pistons' official site reports.
Duren checked out of the game with 6:55 remaining in the quarter and immediately headed to the locker room to for further evaluation. If Duren is unable to return, James Wiseman would likely see most of the minutes at center for the rest of the game.
