Eddie Hearn says Tony Bellew may require surgery for his right hand and could be out for at least five months.
The Liverpudlian broke his hand in his 11th round stoppage victory over David Haye and could require surgery after tearing a capsule.
Bellew will remain in the heavyweight class and is due for one more fight before the end of the year.
“I have spent time with my surgeon so he could assess what is going on and what we do going forward,” Bellew exclusively told Sky Sports. “I will just leave it with him, he knows best.
“I have damaged my hand. In there is some kind of tear; you have some sort of capsule over each knuckle and I’ve split it.
“I’ve also got a fracture in the hand, but when people just say ‘you’ve broken your hand’, essentially I have but it is a fracture.
“It’s going to take a little bit of time, but we’ll take it from there.”
