Tyson Fury has, not for the first time, announced his retirement from the boxing ring.

Former world heavyweight champion Tyson Fury said Monday he had retired from boxing just weeks after suffering a second straight defeat at the hands of Oleksandr Usyk.

Tyson Fury was not pleased with the unanimous decision by the judges to crown Oleksandr Usyk the winner of the heavyweight championship rematch.

The Ukrainian, who forced the pace and repeatedly tagged Fury with his accurate left hook, was awarded the fight 116-112 by all three judges.

Oleksandr Usyk and Tyson Fury were locked in a bad-tempered face-off for a full 11 minutes on Thursday as preparations for their heavyweight rematch turned serious.

Tyson Fury was undecided about a rematch with Oleksandr Usyk after losing his unbeaten record in one of the biggest fights in boxing history.

After long hard conversations I've finally decided to walk away & on my 34th birthday I say Bon voyage," Tyson Fury posted on Twitter.
