(KRON) -- For the first time in 6 years, the Las Vegas raiders played against the 49ers in a regular season game. Although the 49ers won, the atmosphere in the stadium was not completely jubilant, with some fans taking the rivalry too far, getting into fights with one another.
Cellphone video shows several instances inside and outside of Levi’s Stadium where fans beat each other up, punching and yelling at one another.
Eleven people were arrested and 45 were ejected from the stadium during the game, according to the Santa Clara Police Department.
Steven Gomez, a lifelong 49ers fan, went to the game with his cousin and started filming a fight below their seats in the 4th quarter between 49ers and Raiders fans.
At one point, he saw a woman get punched by a man in the stands.
“There was a fight where I was on the upper level and there was one right below us, I think two, which I think was like worse the rumble just started getting bigger and bigger and everybody was like flailing. I was like, Why is everybody getting involved? It was between two people. And then the woman that got hit, her boyfriend, like, was like starting to get emotional,” said Gomes, “He's like, You hit my girl. I was like, this. I just felt by looking at it, it was just going to escalate and escalate and escalate.”
Gomez said he was hesitant to go to the game because he knows some fans get physical.
However, he noted most fans enjoyed the game as normal, but some groups took it too far.
“I love the banter back and forth with them. You don't have to take it to this level. It was always a rivalry I enjoyed as a kid. And it when this happens, it's not safe for us to bring our kids around. We all got to be better,” said Gomez.
Another video showed a brawl outside of Levi’s Stadium where several men pummeled other fans.
Two men were laid out seemingly unconscious in the parking lot as the crowd dissipated.
Gomez noted a beefed-up police presence from Santa Clara police and San Jose police. Officers from Gilroy police were also seen at the stadium to assist.
Ahead of Sunday’s game, Santa Clara police said in a statement:
“Fans can expect to see a significant law enforcement presence and should know that the department implements a strict enforcement policy for individuals who violate the law to provide the highest level of safety and security to all attendees.”
