OAKLAND, Calif. (AP) - Police say a man fell from the upper deck at Oakland Coliseum during Thursday's Raiders-Broncos game and is in serious condition at a hospital.

Oakland police Officer Kevin McDonald says the man fell from the third deck on to the concrete of the lower concourse at about 5:30 p.m., shortly after kickoff.

McDonald says initial reports called the fall an accident, but it remains under investigation.

He says the man is at a hospital and listed in serious condition, but had no further information on his injuries or identity.

The Raiders, who lost to the Broncos 26-13, issued a statement saying the team had no information beyond what authorities are releasing, but the their thoughts and prayers are with the man and his family and friends.
