CHARLOTTE, N.C. — The Panthers say quarterback Cam Newton suffered fractures in his lower back in a car crash in Charlotte.

Panthers spokesman Charlie Dayton said Tuesday outside a hospital that Newton had no other internal injuries and that he would stay overnight for observation.

Television footage showed Newton on a stretcher being placed in an ambulance. The Panthers said he was in fair condition at Carolinas Medical Center.

Photos from The Charlotte Observer showed the 25-year-old Newton smiling as he was attended to by an officer on the ground.
