Bills RB C.J. Spiller undergoes surgery to repair clavicle

Bills running back C.J. Spiller underwent surgery to repair a broken clavicle on Monday, a procedure that will likely end his season. However, coach Doug Marrone would not provide an update on his condition moving forward, per the team's official website.

"We'll wait and see what the doctor says," Marrone said.

Spiller rushed for 287 yards on 69 attempts this season before going down with the injury in Week 7. With Fred Jackson also sidelined with a groin injury, the team will likely turn to Anthony Dixon and Bryce Brown for the majority of the carries against the Jets Week 8.
