Undefeated Australian Heavyweight contender Demsey McKean has signed a multi-fight promotional deal with Eddie Hearn's Matchroom Boxing and will make his American debut on the Demetrius Andrade vs. Jason Quigley WBO Middleweight World Title bill at the SNHU Arena in Manchester, New Hampshire on Friday November 19, live worldwide on DAZN.

The 31-year-old southpaw from Queensland, who is trained by Tony Sims at the Matchroom Elite Boxing Gym in Essex, is the reigning WBO Asia Pacific Champion and the reigning IBF Inter-Continental Champion, belts that rank him at No.11 in the world with the WBO and No. 12 in the world with the IBF.

Demsey (19-0, 12 KOs) was used as a sparring partner by former Unified Heavyweight World Champion Anthony Joshua ahead of his huge showdown with Oleksandr Usyk at the home of Tottenham Hotspur in September before joining the WBC's No.1 ranked Heavyweight Dillian Whyte at his Portugal training camp ahead of his cancelled fight with Otto Wallin.

“I am delighted on my recent signing and to join the Matchroom Boxing team and get back in the ring next week,” said McKean. “I’ve had a brilliant time over the last few months sparring with Anthony Joshua and Dillian Whyte but now it’s time to do it for real and I can’t wait to fight in America. 

“Matchroom have big plans in Australia but it also gives me the chance to box all over the world including the USA and the U.K. I’m looking forward to staying active and to keep climbing the Heavyweight rankings, thank you to Eddie Hearn and Angelo DiCarlo and the Ace Boxing Group team for making this happen."

"I’m very happy to announce Demsey as part of the Matchroom Boxing team as we continue our expansion into Australia," said Matchroom Sport Chairman Eddie Hearn. "Demsey is 19-0 and now ranked No. 11 with the WBO and 12 with the IBF in the Heavyweight division and sits on the cusp of some huge fights. Whilst the plan for us is to begin staging shows in Australia in 2022, we plan on boxing Demsey all around the world starting in the States next week. I’m excited to keep him active and continue to raise his profile globally before we return home for a major fight in Australia."
