Oleksandr Usyk has been tipped for a shock career change after his rematch against Tyson Fury.
Usyk secured victory by split decision when he faced Fury in Saudi Arabia in May.
The Ukrainian became the undisputed heavyweight champion by beating Fury.
However, the pair are set to face each other again in Saudi Arabia in December.
Usyk's coach has suggested that the 37-year-old could subsequently be set for a career change.

Usyk's coach Sergey Lapin claimed that Usyk will 'retire' Fury and could then turn his hand to another sport due to a lack of opponents.
Lapin suggested that Usyk could be involved in MMA against Anthony Joshua or take part in Conor McGregor's Bare Knuckle Fighting Championship.
Lapin told Betway: 'He's proven he's the best of this generation and, once he's retired Tyson Fury, he will consider his options.
'Maybe that's dropping down in weight again, or maybe there's a wildcard option on the table for him.
'Be it in the boxing ring, the MMA cage or even Conor McGregor's Bare Knuckle Fighting Championship.'

Lapin is intrigued by the possibility of Usyk taking on UFC heavyweight star Jon Jones.
'Can you imagine Usyk and Jon Jones fighting to prove they're the baddest man on the planet?
'Or maybe it's a third fight with Anthony Joshua in the MMA cage.
'Maybe it's Jake Paul at cruiserweight, although Usyk would need to fight him with one hand behind his back though to make it fair.'
Usyk previously secured victories against Joshua in 2021 and 2022.
