UFC fans and the whole sporting world was shocked last night when Conor McGregor announced his retirement from MMA.
The 27-year-old was scheduled to fight against Nate Diaz at UFC 200 on July 9, which would have been a rematch of their UFC 196 clash that was won by the American in the second round of the contest via submission with a rear-naked choke hold.
However, last night on Twitter, the Irishman sent out a simple tweet saying: "I have decided to retire young. Thanks for the cheese. Catch ya's later," revealing he would no longer be competing at the event later this year in Las Vegas.

Surprisingly, he wasn't the only UFC fighter to retire on the night, as Nate Diaz and former WWE superstar CM Punk - also known as Phil Brooks - announced their retirements as well on Twitter. However, the validity of these retirement statements is yet to be confirmed.
Punk said in a tweet on his Twitter account: "Well f**k it, I have decided to retire old. Thanks for the shoes @Reebok."
All these retirement decisions are unexpected, but Brooks hasn't even competed in the octagon for UFC since he announced he had signed a multi-fight deal with the promotion in December 2014.
He was expected to have his debut fight against Mickey Gall, who called out Punk in his UFC debut fight in February earlier this year. Dana White then said that fight would take place later this year, possibly at UFC 199.
However, due to injuries still lingering from his days in the WWE, the 37-year-old's UFC debut has been delayed until perhaps later this year, although if his recent tweet is to be believed, it won't be happening at all.
Punk's debut with the UFC is likely to be a massive pay-per-view buy draw because of his fanbase from his time in the WWE, coming over to watch him fight. But with his recent retirement 'announcement', alongside the likes of McGregor and possibly Diaz, it's another huge loss for the promotion.
It's probably safe to assume CM Punk hasn't called it a day, and he isn't retiring from UFC. He's simply joining in on the fun and perhaps taking the mic out of McGregor and Diaz. If this retirement is true however, don't expect this to be the last you hear from him, as there will probably be rumors about him rejoining the WWE once more.
We'll just have to wait and see how all these retirement announcements unfold, and whether or not they are actually true.
