Raiders wide receiver Darrius Heyward-Bey left Sunday's game on a stretcher after being hit by two Steelers defenders in the end zone with 14:31 remaining in the fourth quarter.
Heyward-Bey was surrounded by medical personnel and remained on the ground in the end zone for several minutes. He was ultimately lifted onto a stretcher and gave the home crowd a thumbs-up, signaling that he still had movement in his extremeties.
The Raiders announced Heyward-Bey was unconscious briefly after the hit and was taken to Eden Medical Center with a neck injury.
The main hit came from Steelers safety Ryan Mundy, who started his second consecutive game in place of injured Troy Polamalu. Mundy was not penalized for the hit.
