Sure, football is a violent game, but this video shows that being a spectator can be pretty dangerous too.

At the Buffalo Bills-New York Jets game on Sunday a fan fell from the upper deck of Ralph Wilson Stadium, and the incident was caught by CBS' cameras.

It seems that the fan that fell was skating down a railing when he lost control and fell one level down. He landed on a fan in the deck below. That person reportedly suffered a head injury.

The Bills, by the way, won 37-14.
