Those in San Francisco were delighted with Sunday's play-off win over the Dallas Cowboys, but things turned ugly back in Texas.
The 49ers beat the Cowboys 19-12 at Levi's Stadium, and fans in the Bay Area celebrated long into the night as their side is heading back to another Championship game. But there was the opposite of celebrations over in Dallas, as fights broke out following a watch party at AT&T Stadium.
There were violent scenes at AT&T, with footage circling online of punches being thrown amongst a crowd of people leaving the venue. Security were called to the scene, but police have confirmed that no arrests were made.
