ALLEN PARK — Rookie tight end Brandon Pettigrew's status for the remainder of the season is uncertain at this point. Pettigrew injured his left knee when it appeared to buckle without contact from other players during the Lions' first possession in Thursday's loss to Green Bay. Coach Jim Schwartz said that Pettigrew underwent an MRI Friday morning and the results still were not in.

Schwartz also said that quarterback Mattew Stafford made it through the game with no further damage in his separated left shoulder.
