Tyson Fury announces retirement from boxing

Tyson Fury has declared that he has "officially retired" from boxing.

The British heavyweight, 25, hangs up his gloves just three days after his all-British bout against David Haye was called off for a second time because of a shoulder injury suffered by Haye.

Fury tweeted in angry fashion today: "Hi every1, I have officially retired from boxing. There's to many bent people in the sport. They will have to fuck some1 else. Good by boxin."

'Retirement' is a looser term in boxing than many other sports and the likelihood of never seeing Fury in the ring again may be considered slim.

The 6'9" Mancunian has a perfect 21-for-21 record from his professional fights, with 15 of those victories coming by way of knockout.
