Update: Carr suffered fracture of spinous process of vertebral body. 2-4 Weeks RTP.
Raiders QB Derek Carr left Sunday’s game with a back injury and did not return. Will likely get x-rays. If it’s just a contusion he would likely be fine for Week 5 against the Ravens. If the X-ray shows a fracture of one of the spinal processes, then he could be out for two to four weeks.
