FORT LAUDERDALE, Fla — Miami Dolphins defensive tackle Kendrick Norton, a former University of Miami standout, was involved in a two-car accident early Thursday morning that resulted in his left arm being amputated.

Norton’s left arm had to be amputated by paramedics at the scene for him to be removed from the rolled-over vehicle, sources tell the South Florida Sun Sentinel. According to the sources, he is in critical condition at Jackson Memorial Hospital’s Ryder Trauma Center in Miami, though his injuries are not believed to be life-threatening.
