It was chaos in the stands after the Giants and 49ers game on Thursday night. Fans of both teams engaged in a wild fistfight, resulting in bloodshed. Witnesses reported that the fight started when one fan threw a beer that landed on a woman, causing tensions to escalate rapidly.

Video footage obtained by TMZ Sports shows the violent brawl unfold moments after the liquid was spilled. It seems that the trash-talking between the fans finally reached a boiling point.

During the fight, one fan wearing a Joe Montana jersey was repeatedly punched in the face, resulting in a gruesome nosebleed. Nearby, two Giants fans were seen throwing powerful punches at a man in Niners gear, leaving a cut above his right eye.

However, the Niners fan managed to defend himself and landed a few punches of his own before making a quick escape from the area. By the time authorities arrived at the scene, most of the combatants had already fled.

The Santa Clara Police Department is currently investigating the incident. This fight was not the only one that occurred at the stadium on Thursday. Just hours before, another scuffle broke out, and a man was seen pulling a woman’s hair in a different part of the venue.
