Fan violence marred games in Los Angeles and Minneapolis during week three of the NFL season.

Sunday’s clash between the Los Angeles Rams and San Francisco 49ers saw a wild brawl take place in the stands at the SoFi Stadium.

It stemmed from a dispute between a man in a Cooper Kupp jersey and a rival wearing a George Kittle shirt.

Their argument soon turned physical as the Niners fan asked to be hit in the face and was promptly caught with a left jab.

A woman could then be seen jumping in by squaring up to the Rams supporter, even swinging punches of her own.

However, the Kupp backer then decked her with a single punch as all hell broke loose.

The man in the Kittle jersey rushed back in as around five onlookers joined the fracas, which dispersed once the Niners fan had been floored by a different Rams supporter.

On the field, the Rams came from behind to secure a 27-24 victory over last season’s Super Bowl runners-up.

Meanwhile, another fight also broke out in Minneapolis as the Minnesota Vikings took on the Houston Texans.

Fan footage showed a melee in the stands involving around half a dozen people.
