Conor McGregor has published a cryptic tweet, with the words that he has "decided to retire young".

The UFC featherweight champion is due to take on Nate Diaz in a welterweight rematch at UFC 200 this July. 

The 27-year-old Dubliner's tweet this evening read, "I have decided to retire young. Thanks for the cheese. Catch ya's later".

His coach John Kavanagh, as well as Diaz, also tweeted cryptically shortly after:

Well was fun while it lasted

I guess my work here is done I'm retiring too✌🏼️👊🏼

McGregor is currently training in Iceland based on his most recent updates:

Thanks for the cheese.
Catch ya's later.
