British heavyweight boxer, Tyson Fury, say fellow Briton, Anthony Joshua was finished as a boxer after losing his world heavyweight titles to Andy Ruiz Jr.
Fury, also a previous IBF, WBA and IBO champion, fights German underdog Tom Schwarz in a non-title bout in Las Vegas on Saturday night.
The big Briton said Joshua had shown against Ruiz that he did not want to be in the ring.
Mexican-American Ruiz stopped 29-year-old Joshua in seven rounds at New York’s Madison Square Garden in a major upset on June 1.
Joshua’s promoter Eddie Hearn has said there will be a rematch, probably in November or December, with the venue to be decided.
Fury is also scheduled for a rematch with WBC champion Deontay Wilder, with a date to be set.
The Briton, whose fight with Schwarz is the first of a multi-fight broadcast deal agreed with ESPN in February, is the only boxer Wilder has faced and not defeated.
That was after the pair battled to a draw in December in Los Angeles.
Frank Warren, Fury’s British promoter, said in January that his man was bigger box-office than Joshua.
