UFC Featherweight Champion Conor McGregor confused the sporting world on Tuesday when he abruptly tweeted he had decided to retire.

John Kavanagh, who runs Straight Blast Gym and has trained and coached McGregor, conspicuously tweeted “it was fun while it lasted.”

Ariel Helwani of MMAfighting.com tweeted he talked with sources that were “adamant” McGregor wasn’t joking or pulling some sort of stunt.

The announcement was certainly random. McGregor is only 27 years old and at his physical peak, and is currently one of the most dominant, marketable fighters in the entire sport. McGregor was scheduled for a rematch against Nate Diaz, the man who gave him his first UFC loss in March, on July 9 at UFC 200.

Diaz joked on Twitter that he was also retiring.
