Calvin Johnson , the Lions' rookie wide receiver, was on the way to having a big game before a back injury limited his playing time. Johnson had two catches for 44 yards. Johnson gained 11 yards on an end-around and was pulled down from behind by Bears cornerback Charles Tillman . He aggravated a back injury, sustained in the third game against the Eagles, and played sparingly the rest of the game. "I just fell on the same spot," Johnson said. "That's why my play was cut. It took a while to loosen up. It was still pretty sore."
