Pettigrew (knee) didn't participate in Wednesday's practice, Tim Twentyman of the Lions' official site reports.

EDGE Analysis

In the current campaign, Pettigrew has been beset by injuries to his hamstring and now knee, limiting him to two appearances in six games. Fellow tight end Eric Ebron (calf) appears to be closing in on a return himself after practicing on a limited basis last week, but the week of preparation will ultimately determine who composes the Lions' TE corps Sunday versus the Vikings.
