Conor McGregor was scheduled to face Nate Diaz at UFC 200 on July 9 in what is highly anticipated to be one of the biggest pay-per-views in the promotions history.
It was going to be a rematch of their clash at UFC 196, where the American caused the Irishman to submit via a rear-naked choke hold in the second round. It was McGregor's opportunity for redemption for the loss.
But the fight may never happen. According to his official Twitter account, The Notorious has announced his retirement from the sport, simply tweeting: "I have decided to retire young. Thanks for the cheese. Catch ya's later."

This announcement has come much to a surprise for many across the MMA and sporting world, whether it be his fans or journalists alike. However, we must take it with a pinch of salt at the moment, as it's unclear if the 27-year-old has tweeted the message himself, or whether his account has been hacked.
The UFC is yet to confirm his retirement, and if it is true, the main event of UFC 200 would have to be changed.
The tweet comes one week after Joao Carvalho died from injuries suffered during a fight earlier this month that was attended by McGregor in Dublin, Ireland. He was there for his teammate, and Carvalho's opponent, Charlie Ward.
