"It's a muscle strain so that was good news," he said.
Fox said Dumervil's status will remain day-to-day, but the injury won't threaten the defensive captain's season.
Dumervil injured his shoulder reaching out to strip the ball from Panthers quarterback Cam Newton on the final play of the first quarter. He was credited with the sack and forced fumble. He returned for one more play, but left in the second quarter and watched from the sideline as his linemates dominated the Panthers up front.
