Njoku (knee) returned to a full practice Thursday, Nate Ulrich of the Akron Beacon Journal reports.
Njoku is thus on track to play Sunday against the Cardinals. The tight end didn't make much of a mark (one catch for four yards) in his return to action from a wrist injury in Week 14, but he's at least in a decent position to bounce back this weekend, given Arizona's struggles containing tight ends this season.
