An aggravated Joe Joyce talked trash like never before Thursday during a press conference to officially announce his fight against Joseph Parker.

The British knockout artist typically takes a reserved approach to promotional events, but the delay in scheduling this fight with Parker clearly has annoyed Joyce. The London native predicted another knockout September 24 in Manchester, England after Parker bickered with Frank Warren, Joyce’s promoter, regarding who was at fault for their fight not coming together for July 2, as initially planned.

“Now the fight’s happening,” Joyce said. “It’s to give the fans and all the people what they want, because it’s gonna be a great fight. And yeah, I can’t wait to just knock him out, just for all this like long time waitin’ and all this messin’ about, when we coulda had it in July. And you just wasted my time.”

Joyce (14-0, 13 KOs), the WBO’s number one-ranked heavyweight contender, has knocked out 93 percent of his professional opponents. Parker (30-2, 21 KOs), a former WBO heavyweight champion who is ranked second by the WBO, has lost only a pair of 12-round unanimous decisions to former IBF/IBO/WBA/WBO champ Anthony Joshua (24-2, 22 KOs) and contender Dillian Whyte (28-3, 19 KOs).

New Zealand’s Parker has won six consecutive fights since he lost back-to-back bouts to Joshua and Whyte in 2018. Parker promised a knockout of his own Thursday, but Joyce, whose granite chin has compensated for his defensive deficiencies, dismissed that possibility.

“I think he’s gonna try his hardest to try and hit me, and you know, whatever he’s done in the camp,” Joyce said. “But, at the end of the day, I’m gonna win and I’m gonna knock you out.”

Parker reminded Joyce that he will be the most accomplished opponent of a five-year pro career in which the 2016 Olympic silver medalist most notably has stopped then-undefeated Daniel Dubois (18-1, 17 KOs) in the 10th round of their October 2020 bout in London. American contender Bryant Jennings (24-4, 14 KOs) is the only opponent who has taken Joyce the distance as a pro.

“Listen, but he’s never fought anyone like me,” Parker said. “He said he fought people like me in the amateurs. We’re not in the amateurs. We’re professional.”

Joyce, who will turn 37 five days before he opposes Parker, and Parker, 30, were supposed to fight July 2, but negotiations ceased at some point after Parker signed with Boxxer, an upstart promotional company based in England. Warren, with Joyce and Parker standing on each side of him, announced during BT Sport Box Office’s telecast of the Tyson Fury-Whyte pay-per-view show April 23 at Wembley Stadium in London that they would fight next.

With the Parker fight in doubt, Joyce instead stopped German veteran Christian Hammer (27-10, 17 KOs) in the fourth round of their July 2 bout at OVO Arena Wembley in London.

BT Sport Box Office will televise Joyce-Parker in the United Kingdom and Ireland as the main event of a pay-per-view show September 24 from AO Arena in Manchester. An American broadcast partner hadn’t been secured as of Thursday, but ESPN+ is expected to stream Joyce-Parker in the United States.
