Tyson Fury Announces His Retirement From Boxing

Tyson Fury announced on Twitter that he has retired.

Fury posted a profanity-filled tweet not just announcing his retirement, but also took the opportunity to talk down the entire sport of boxing.

The current unified heavyweight champion had been under a lot of scrutiny in the past year since defeating Wladimir Klitschko last year. Their rematch had been called off for the second time last week as Fury was deemed “medically unfit” to compete.

While no official announcement had been made on why he is still not cleared to fight, Fury was submitted to a random urine test Sept. 22 in Lancaster, England. The the results came back positive for the substance benzoylecgonine, the central compound found in cocaine and the marker for a positive test for the banned substance. Fury also tweeted a meme of his face replacing Scarface character Tony Montana sitting in front of a large amount of cocaine.

Fury’s doctor believes that he may be suffering from mental health issues, according to reports.

When the cancelation of the second rematch attempt with Klitschko was announced, it was also announced that Fury would undergo treatment. Klitschko and Fury were originally going to fight on July 9, but Fury suffered an ankle injury weeks before the fight and could not compete.

It is still not sure whether or not he will follow up on the retirement. Fury won the WBA (unified), WBO, IBO, The Ring magazine, and lineal heavyweight titles from Klitschko in 2015.
