Peppers hit on Stafford near the end of the first half knocked the former No. 1 pick out of the game with a right shoulder injury.
"I just wanted to know how he was doing and what happened because he's a great young player, and I don't want to see him out for the whole year," Peppers said. "I was just checking up on him seeing if he'll be back."
The Bears prized free-agent acquisition drove Stafford's right shoulder into the turf, somewhat reminiscent of the preseason play when Bears backup quarterback Caleb Hanie suffered a shoulder injury in San Diego. The Lions' offense never really recovered after Stafford was lost for the day.
"I was just doing my job," Peppers said.
