Raiders' Heyward-Bey won't play Sunday

The Oakland Raiders ruled wide receiver Darrius Heyward-Bey out of Sunday's game against the Denver Broncos.

Heyward-Bey took a hard shot to the head from Pittsburgh Steelers safety Ryan Mundy last week and was hospitalized overnight with a concussion and neck injury. He hadn't practiced at all this week but had been listed as doubtful to play this week until the Raiders announced Saturday afternoon that he wouldn't see action.

Raiders tight end Richard Gordon also won't play Sunday.
