Joe Joyce’s concrete chin has been perhaps his greatest strength during his steady climb toward a heavyweight title shot.

The hulking knockout artist’s ability to take even the flushest punches from big, strong opponents has helped him overcome defensive flaws that might’ve led less durable boxers to knockout defeats. Joseph Parker predicted that’s all about to end.

The former WBO heavyweight champion claimed that he’ll punch through Joyce’s aura of invincibility and knock him out when they meet September 24 at AO Arena in Manchester, England.

“I will hurt him,” Parker said. “Yeah, I will hurt Joe. … I’m gonna beat him, get him out of there and get the win. That’s what I’m gonna do.”

The 6-foot-6, 265-pound Joyce also predicted a knockout. In nearly five years as a pro, only American veteran Bryant Jennings has gone the distance with London’s Joyce (14-0, 13 KOs), who defeated Philadelpha’s Jennings (24-4, 14 KOs) by unanimous decision in a 12-rounder in July 2019 at O2 Arena in London.

Something must give, however, because Parker (30-2, 21 KOs) has not been knocked out in 32 professional fights. Former IBF/IBO/WBA/WBO heavyweight champ Anthony Joshua (24-2, 22 KOs) and British contender Dillian Whyte (28-3, 19 KOs) topped Parker by unanimous decision in back-to-back 12-rounders in 2018, but he has won six straight bouts since suffering his lone losses.

When Joyce joked about Parker’s punches amounting to tickles, the 6-foot-4, 250-pound Parker promised that Joyce will finally feel what 93 percent of his pro opponents have learned when they’ve encountered “The Juggernaut.”

“I’m gonna beat your ass up and get you out of there and get the win and then move on,” said Parker, whose past three fights have gone the 12-round distance. “Actually, oh sorry, you’ve locked me into a rematch clause. So, I’m gonna have a rematch with you again in December. I don’t need a rematch clause because I back myself.”

Joyce took offense to Parker’s reference to their rematch clause.

“I back myself, but, you know, I’m the ‘A’ side, so I’m entitled to my rematch clause,” Joyce said. “The fight’s on now, and I’m gonna put some dents into your face.”

Joyce, 36, and Parker, 30, will headline a BT Sport Box Office pay-per-view show in the United Kingdom and Ireland. Joyce opened as a slight favorite (-166/+130), according to FanDuel.
