It was supposed to just be a watch party at the AT&T Stadium as Dallas Cowboys fans expected to win against the San Francisco 49ers. However, it was the Niners who won instead, causing not just heartbreak for Cowboys fans but also a brawl at a watch party just outside the stadium.

The Dallas Texas TV Twitter account posted videos of the brawl after the Cowboys' loss and elimination from the NFL playoffs. The second video shows security arriving to try to break up the brawl in one of the nearby beer stands.

It is still unclear why the brawl happened or who started the fight, according to Fox News.

Brawl Was Between Dallas Cowboys Fans

While it is still not known how the fight started, what is known is that the Dallas Cowboys fans were fighting each other outside the stadium. According to TMZ, one fan who was wearing a CeeDee Lamb jersey slammed a man wearing an Ezekiel Elliott jersey.

Fists were then flying, though other Cowboys fans did try to break up the fight. However, the fight soon ended up in an all-out brawl, with security stepping in.

There were actually multiple brawls around the AT&T Stadium, as the fight between the men above was different from the brawl near one of the beer stands. The latter reportedly happened as the game was still going on, but it was already clear that the Cowboys were not going to advance in the NFL playoffs.

However, even with security already intervening, Cowboys fans were still trying to get at each other's throats. It is unknown if the police made any arrests after the fight, however.

San Francisco 49ers Eliminate the Dallas Cowboys for the Second Year in a Row

After beating Tom Brady and the Tampa Bay Buccaneers, the Dallas Cowboys looked very hot coming into Sunday's NFC divisional round game. They had one of the best defenses in the league, but it seems that it was not enough to beat the San Francisco 49ers, who went on to win that defense-heavy match, 19-12.

The Niners put forth a defensive clinic in that game at Levi's Stadium, shutting down the Cowboys' offense with just 282 yards of offense on 4.7 yards per play, according to ESPN.

The San Francisco squad also saw one of the best plays during the NFL playoffs so far, as San Francisco 49ers quarterback Brock Purdy threw a beautiful pass to tight end George Kittle, who was darting down the middle of the field to score a touchdown.

After eliminating the Cowboys, the San Francisco 49ers will next face the Philadelphia Eagles, and the winner of that match will be heading to the Super Bowl. They previously eliminated the Cowboys in last year's playoffs as well.
