ALLEN PARK, Mich. — Lions coach Jim Schwartz has not ruled out Matthew Stafford from returning Sunday against San Francisco after missing two games with a shoulder injury.

Schwartz said Monday that he hopes to decide on a starting quarterback by Wednesday.
If Stafford can’t play against the 49ers, Schwartz will decide between Daunte Culpepper and Drew Stanton. Culpepper was pulled at halftime of a 31-24 loss to Arizona last weekend, and Stanton led a second-half rally.
Stafford hurt the shoulder Nov. 22 against Cleveland, and gained some fame when he put himself back in the game after getting hurt and threw his fifth touchdown pass on an untimed play.
He aggravated the injury in the fourth quarter against Cincinnati on Dec. 5.
