Video: Street fight erupts after Matt Brown is allegedly attacked by ex-coach at UFC fighter hotel in Brazil

It's been en eventful trip to Brazil for Matt Brown.

"The Immortal" was allegedly on the receiving end of a sucker punch from his former jiu-jitsu coach Rodrigo Botti earlier today (Sun., May 15, 2016) at the UFC fighter host hotel in Brazil. According to the report via MMA Fighting, Botti decked Brown from behind and tried to escape via taxi.

However, one of Matt's friends, Vinicius Lemos, caught up to him and proceeded to beat the living snot out of him as evidenced by the video below:

UFC officials -- including former World Extreme Cagefighting (WEC) president Reed Harris -- were on scene to break up the melee and call police officials. The promotion subsequently released a statement on the incident.

"UFC is aware that welterweight contender Matt Brown was allegedly attacked today by a former acquaintance at the UFC 198 host hotel in Curitiba, Brazil. UFC has been in communication with local authorities to gather more information relative to the alleged attack, and is reviewing security measures at the hotel. Fortunately, Brown was uninjured in the situation and will return home to the United States later today as planned."

Ironically enough, Botti is the one pressing charges against Lemos for retaliation. Meanwhile, Brown himself has yet to file charges against Botti, according to the report. However, things aren't looking good for Botti, as he can be heard in the video saying "like he did to me," after Harris tells him saw him hit Brown.

According to Colleen Brown, Matt's wife, the two have a history of physical altercations.

Not a random fan who attacked Matt. It was Rodrigo Botti who is an absolute psycho.

In Feb 2015 Matt wore wrestling shoes on mats and Botti got pissed..shoved Matt so Matt fought back. Botti called cops like a wimp.

Indeed, in February 2015, it was reported that Matt had been involved in a scuffle in his gym with one of his coaches.

The alleged attack on Brown comes a day after he was submitted by Demian Maia at the UFC 198 pay-per-view (PPV) event in Curitiba, Brazil (see it here).

On the way to the cage for his fight against Maia, Matt had to fend off fans who kept taking swings at him, getting into with one in particular who decided it would be a good idea to grab a hold of his hoodie.

A day before at the official weigh-ins, "The Immortal" sent Brazilian fans in attendance into a fury after he gave his back to them and flipped them the bird while on the scale.
