Charles Martin wants revenge for his defeat to Anthony Joshua, and believes the Briton’s loss to Oleksandr Usyk was ‘karma’.
Joshua won the IBF belt from Martin in 2016, making Martin’s 85-day reign as champion the second shortest in history.
Martin claims he had an injury going into the fight and told Sky Sports that something similar may have happened to Joshua before his defeat to Andy Ruiz Jr.
"Rumours spread that the dude was hurt," Martin said. "I was hurt [before I fought Joshua].
"What goes around comes around. It's called karma.
"I looked bad against Joshua when I was already hurt. Then he got caught by Andy when he was already hurt. Karma.
"I'll never know, and the world will never know, what would have happened against Joshua if I wasn't badly hurt 10 days before our fight.
"Andy got a lucky punch. Andy has no pop. He's fast but has no power."
The 35-year-old heavyweight hopes that he will avenge his defeat to Joshua.
"It will happen. He's also got two Ls now. It ain't for nothin'. It ain't for the money,” he explained.
"You get one up on me? I'll see you later. I'm from St Louis - if you get one up on me, I'll come back around the block and get one up on you!”
