Newton was alert but in pain at the scene of the accident, and sustained multiple fractures to his back. Newton, along with the other driver, were taken to a nearby hospital with non-life-threatening injuries.
"Further testing revealed that Cam Newton has two transverse process fractures in his lower back and no further internal injuries," the Panthers said in a statement Tuesday.
The former Heisman Trophy winner is being held for observation, and no timetable has been set for his return to the field.Dallas Cowboys quarterback Tony Romo suffered a similar injury earlier this season, and missed one game.
Newton was recently in the news on Sunday, when he and the Panthers trounced the New Orleans Saints. A celebration by Newton, including his trademark Superman move, sparked a brawl between the two teams. The Panthers are currently one game out of the division lead in the NFC South.
