Joseph Parker's WBO heavyweight world title defence against Hughie Fury is a "50-50" fight, according to former champion David Haye.
Parker will this weekend leave his Las Vegas base for London to acclimatise and prepare for the fight against Fury in Manchester on September 23 and will train mostly at Haye's gym.
The pair struck up a friendship the last time Parker was in London, but the 36-year-old Haye, who has been out of action since March when he ruptured his Achilles in the defeat to Tony Bellew, believes the fight will go the distance.
"Joseph Parker hasn't put a foot wrong as a professional and neither has Hughie Fury," Haye told boxing channel IFL TV.
"I think it will be close. Although Joseph Parker is the champion, he's coming to foreign territory and if it goes to points then he might not get that much love from the judges. I know it shouldn't work that way but he's coming over here to fight on a foreign promoter's event.
