Pettigrew may see an expanded role Sunday with Eric Ebron unlikely to play due to a hamstring injury. The Lions have not targeted Pettigrew more than three times in a game this season, thanks to the addition of Golden Tate as a more viable No. 2 receiver and the arrival of Ebron. Pettigrew played 49 snaps in Week 6, and should see an even larger role in the passing game as Calvin Johnson (ankle) was unable to practice all week and seems unlikely to play as well.
