Allen Park — Lions offensive tackle Jason Fox, who has played parts of just two games this season because of groin and knee injuries, was back at practice on Wednesday.
It was a welcome sight because two other tackles, starters Riley Reiff (hamstring) and Corey Hilliard (knee) were unable to practice. Veteran Barry Richardson, signed Tuesday, was also working.
Receiver Calvin Johnson (knee) did not practice Wednesday, nor did defensive tackle Andre Fluellen (unspecified) and safety Louis Delmas (knee).
Cornerback Rashean Mathis, who is battling a groin injury, went through warmups and position drills.
