UFC 229 was marred by an ugly brawl at the conclusion of its main event.Conor McGregor's mixed martial arts return - after a near two-year hiatus - fell flat as he tapped out midway through the fourth round against lightweight champion Khabib Nurmagomedov.But the 30-year-old Russian fighter began a brawl by the octagon moments after preserving his undefeated record.Nurmagomedov jumped into the crowd to attack Dillon Danis, a member of McGregor’s team."I don't think that was calculated," said UFC commentator Joe Rogan. "I think that was in the moment, he [Khabib] was full of passion."Conor is going to come out the victim here and Khabib is going to have a very difficult time getting a visa or a green card."This is incredibly disappointing."

Oscar De La Hoya's tweet

One man who seemed to see the brawl very differently was retired boxer Oscar De La Hoya.

The 45-year-old American became an MMA promoter earlier in 2018 and posted a tweet about McGregor - and his fans - after the fight.

De La Hoya was pointing the finger of blame at the Irish fans but deleted the tweet after receiving plenty of abuse.

Irish boxer Michael Conlan, who is a friend of McGregor's, replied to the controversial tweet and spelled out what happened.

De La Hoya has since attempted to distance himself from the tweet posted from his account.

"My account was hacked, I just want to make you are that this was not me." wrote De La Hoya on Twitter.

"Last night was an unfortunate turn of events during one of the biggest and important fights in UFC history."

The general consensus is that De La Hoya was telling porkies.

Former UFC light heavyweight champion Chuck Liddell was furious after witnessing the chaos after the fight.

“Incredible performance by both fighters,” Liddell wrote. “But to end it like they did was a huge embarrassment to the sport.”

“We (fighters) are sportsmen and champions and we should hold ourselves to a higher standard. We owe it to our fans and the sport itself.

“I don’t know when things started turning into some kind of s— show?

“Unfortunately, when you allow more and more B.S. during weigh ins and outside of fights, you only slap fighters on the wrist for acting like barbarians and then offer them bigger contracts and reward them for this behaviour.

“There is no penalty for their actions and it condones this type of behaviour and consequently our sport loses its sacred respect.”
