Tony Bellew v Oleksandr Usyk: I'd fight King Kong but I must stop, says Briton
Briton Tony Bellew suggested undisputed cruiserweight world champion Oleksandr Usyk could be his final opponent because "I'm a danger to myself".
The 35-year-old faces Ukraine's Usyk, who has won all 15 of his professional fights, at the Manchester Arena on 10 November.
"The sooner I stop, maybe the better because I'll fight anyone - King Kong, if I was allowed I would," Bellew said.
"I've had an exit strategy planned for quite a while now," he told BBC Sport.
"If I don't stop now, my wife will divorce me after four or five months and that's not the plan," he added.
"I am a risk, emotionally and physically, I am just a risk. I'm dangerous, I'm a danger to myself."
Bellew had earlier told a news conference: "Babe, if you're watching this, I promise you this will maybe be my last one."

The Liverpool fighter, who is dropping down to cruiserweight after twice beating David Haye at heavyweight, has lost only two of his 33 bouts, the most recent defeat coming in December 2013 against Canada's Adonis Stevenson.
He said in Usyk he is facing a "monster" that "no one wants to fight".
Bellew continued: "Just one wrong step, one wrong manoeuvre, and it's over.
"He is an amazing fighter. I will not admire him, I will fight with everything I've got.
"You will have to nail me to the floor to keep me there - and you could do it, I'm not stupid, but I don't think you can."
'He made the ultimate sin, saying my name'
The pair faced off in Manchester on Monday, having posed in the ring at Wembley during Anthony Joshua's win over Alexander Povetkin on Saturday.
"He passed a comment after Saturday's stare down, and the comment that he passed was he thinks I am arrogant," added Bellew.
"He says he believes I am arrogant, but it is not arrogance he sees. For the first time in his whole career he sees a man looking back at him that believes he can win, and not a man who believes he is just going to lose."
Usyk, 31, became the first boxer in history to hold all four major world championships at cruiserweight - WBO, WBC, WBA and IBF - when he beat Murat Gassiev to win the World Boxing Super Series in July.
"I was on my honeymoon and for one reason or another I was stood there watching Oleksandr beat up Gassiev on a mobile phone," Bellew said. "He then made the ultimate sin; he says my name.
"It didn't take long. As soon as he said my name, I knew. The world is going to write me off, but the more you write me off, the more I want to fight."
