Santa Clara police told ABC 7 that two male victims were taken to the hospital and two men were arrested for felony assault. Police said it is the second time since the stadium opened in July that there has been a reported assault at the facility.
It is also the second time in three weeks that fans wearing 49ers attire have gotten into a fight that was captured on camera.
During this incident, a fan wearing a Frank Gore shirt punched a man wearing a Colin Kaepernick jersey, knocking the man to the ground. The fan in the Gore shirt and a fan in an Aldon Smith jersey then landed several punches on a fan in a NaVorro Bowman jersey.
The 49ers beat Kansas City 22-17.
During a game between the 49ers and the Arizona Cardinals at University of Phoenix Stadium in Glendale, Arizona, on Sept. 21, several people were involved in a bloody brawl, sending several spectators down a stairwell as security tried to stop the fight.
That same day, fans in Philadelphia started a fight in the upper deck of the Eagles' stadium.
