Reports: Fan jumps or falls from upper deck in Oakland

A fan plummeted from the upper deck at the Oakland Raiders' home game Thursday, and he was hospitalized in serious condition, according to multiple media reports.

The Oakland Tribune reported that the fan apparently jumped, but other reports indicated that the fan fell. Team and police officials did not release the name of the fan or other details.

It was also unclear whether the incident at O.co Coliseum in Oakland happened before or during the game, which the Raiders lost 26-13 to the Denver Broncos.

The Raiders issued a statement that included no specific information about the incident but said, "(The team's) thoughts and prayers are with this gentleman and his family and friends."
