MMA Star: ‘I’ve Decided to Retire Young’

UFC star Conor McGregor seemingly and abruptly announced his retirement Tuesday afternoon with a single tweet. "I have decided to retire young," he wrote. "Thanks for the cheese. Catch ya's later." The 27-year-old star is scheduled to fight Nate Diaz at UFC 200 in early July—a rematch of their fight earlier this year.
