Bellew was beaten by Oleksandr Usyk at Manchester Arena on Saturday night in a battle for the undisputed cruiserweight championship of the world.
The Ukrainian inflicted Bellew’s third loss of his career with a stunning eighth-round knockout.
The Brit was always going to retire after the fight, no matter what the result, though hoped to go out on a high.
Bellew will go down as one of the greats of British boxing having previously been cruiserweight world champion.
He also beat David Haye twice in epic heavyweight clashes before dropping down a weight again to take on Usyk.
And Bellew revealed that he will no longer be Tony Bellew with his alter-ego now gone forever.
