Oakland Raiders wide receiver Darrius Heyward-Bey will be kept in the hospital overnight after being knocked unconscious Sunday by Pittsburgh Steelers safety Ryan Mundy.
Heyward-Bey is listed in stable condition according to a team spokesman, per the Oakland Tribune.
During his postgame press conference, Raiders head coach Dennis Allen said he only knew the Maryland product suffered a concussion.
Heyward-Bey was injured in the fourth quarter when Mundy nailed him with a vicious helmet-to-chin hit. He lost consciousness before falling to the turf in the end zone.
“I didn’t go in there trying to hit him with my helmet,” said Mundy. “Things like that happen so fast. He may have come down to the level of my helmet. I have to see the replay, I don’t know.”
The replacement officials did not call a penalty on the play.
Heyward-Bey remained motionless on the field for more than 11 minutes before he was immobilized and carted off. He managed to give the Oakland crowd a thumbs up as he was being driven off the field.
He recorded two catches for 14 yards with one touchdown prior to the injury.
The Raiders went on to win the game 34-31 at the O.co Coliseum.
