Charlotte, NC (SportsNetwork.com) - Carolina Panthers quarterback Cam Newton is in fair condition at a Charlotte hospital after being involved in a two-car accident on Tuesday afternoon.

The Panthers later announced that Newton suffered two transverse process fractures in his lower back during the crash but no other internal injuries. The 2011 No. 1 overall pick will remain at Carolinas Medical Center overnight for further observation.

According to the Charlotte Observer, the accident occurred at about 12:50 p.m. ET near Bank of America Stadium. The paper said one of the vehicles involved in the accident overturned.

A picture from the Observer's Twitter page showed Newton conscious and smiling while being examined by medical personnel.

Newton's status for Sunday's contest against Tampa Bay is uncertain. Dallas Cowboys quarterback Tony Romo missed one game earlier this season after sustaining a similar injury to his back against Washington on Oct. 27.
