Cam Newton's surgically repaired shoulder has been the focus for much of the Carolina Panthers' preseason, but the focus turned to the franchise quarterback's left foot and ankle after a first-quarter sack in Thursday night's 10-3 preseason loss at New England.
Team medical staff examined Newton's left foot on the sideline after the sack, his second in three series. The 2015 NFL MVP then walked to the locker room, the team later announcing he would not return.
After the game, coach Ron Rivera said Newton was placed in a walking boot and was being taken for X-rays but didn't have further information.
