Two men were taken to a Buffalo hospital after one fell from the third deck of Ralph Wilson Stadium and landed on the other during the Bills' game against the Jets.
According to a Rural Metro ambulance service report, the man who was hit by the falling man sustained a head injury. The man who fell sustained a shoulder injury, which was not considered life-threatening.
Rural Metro could not reveal the names of the two men or release any further details.
The accident occurred during the second quarter of the Jets' 14-37 loss.
The Bills said both men were treated immediately and taken to hospital for observation.
In a statement Monday, Bills President and CEO Russ Brandon called the behavior of the fan who fell irresponsible and said he has been banned from the stadium.
"The irresponsible behavior that occurred at yesterday’s game by the fan who fell from the upper deck is a violation of our Fan Code of Conduct and cannot, and will not, be tolerated," Brandon said. "The vast majority of our fans who attend Bills home games at Ralph Wilson Stadium do so in a responsible manner and we continue to work diligently to eliminate those individuals who violate our Fan Code of Conduct from game days at our stadium."
Brandon also said the team is cooperating with the Erie County Sheriff's office in the investigation.
