The Raiders are down their top two receivers in their AFC West matchup with the Broncos.

After Michael Crabtree was ejected in the first quarter for getting into a fight with Broncos cornerback Aqib Talib, Raiders receiver Amari Cooper left in the second quarter with an apparent neck injury.

Cooper tried to haul in a first-down pass over the middle from quarterback Derek Carr, but was hit mid-air by Broncos safety Darian Stewart. Though the hit appeared to be clean, Stewart was penalized for unnecessary roughness.

Cooper dropped his head as Stewart approached and Cooper's shoulder collided with Stewart's back, causing Cooper's neck to bend awkwardly.

A cart came out for Cooper, but he was able to stand and slowly walked off the field and straight to the Raiders locker room at The Oakland Coliseum. Cooper had scored the game's first touchdown, a 9-yard reception to give Oakland a 7-0 lead.

The Raiders extended their lead before halftime on a Marshawn Lynch touchdown run to hold a 14-0 advantage.
