Britain’s former world heavyweight and cruiserweight champion David Haye announced his retirement on Tuesday following two successive defeats to fellow Englishman Tony Bellew.

The 37-year-old — who won 28 of his 32 bouts including 26 knock outs — unified the cruiserweight world division then was crowned world heavyweight champion in defeating the ‘Beast from The East’ Russia’s Nikolay Valuev in 2009.

Haye implied he was retiring after that defeat and on several occasions prior to that had pledged to leave the sport before he was 31 declaring ‘That’ll be 20 years of getting punched in the face, which is a long enough time.’
