Dillian Whyte has verbally bashed former WBO heavyweight champion Joseph Parker.
The two heavyweight rivals will collide next Saturday night at the O2 Arena in London, as the main event of a Sky Sports Box Office card.
Whyte is coming off a brutal knockout victory over Lucas Browne, while Parker went the full distance with unified champion Anthony Joshua back in March.
Parker is the only boxer to last the distance with Joshua.
But Whyte is not impressed.
Back in December of 2015, Whyte fought a war with Joshua. The current IBF, WBO, WBA, IBO champion broke him down and stopped him in seven rounds.
During that fight, Whyte suffered a bad shoulder injury, which required surgery afterwards.
He says Parker knew he was far behind on the scorecards and was too scared to turn the tide by taking the "fight" to Joshua.
"Six or seven rounds into a fight, if you're in the home fighter's country against a world champion and a golden boy, you know you're behind on the scorecards, there comes a time when you've got to go after it," Whyte stated during 'The Gloves Are Off' on Sky Sports.
"I feel that he was too much of a coward to make that decision. He had waited for that opportunity for his whole life. When I fought Joshua my shoulder went in the second round. My coach wanted to pull me out. I knew I still had enough power to land a one-hitter-quitter but unfortunately I got stopped. I could have done what everybody does and produced medical records after.
"That's why I think he was a coward - he didn't get hurt at any point in the fight. He didn't get stung but he didn't make the decision to go after him. Now he regrets it. To me, that's a coward's mind-set."
