Anthony Joshua described his stunning defeat to underdog Andy Ruiz Jr. as "a minor setback" but some in the fight game are wondering where Britain's damaged heavyweight hope goes from here.

Joshua's promoter Eddie Hearn has already said there will be a rematch, possibly in England or Wales later this year, and that is a must-win for the 2012 Olympic super-heavyweight champion.

Former IBF cruiserweight world champion-turned-commentator Glenn McCrory told TalkSPORT radio on Monday that Joshua might never recover from one of the biggest upsets in heavyweight history.

"He’s bottom of the pile. He got beaten up by Andy Ruiz," he said of the weekend fight in New York.

"I think he’s finished. It’s not just the defeat, anybody can get defeated, but the nature of it.

"Andy Ruiz is not an elite athlete, he is not a heavyweight great. He will not go down in icons of legends at all, but he is a tough kid and he seized his opportunity."

The 29-year-old had hoped to conquer America on his debut at Madison Square Garden and instead comes away having handed his four titles (IBF, WBA, WBO and IBO) to Ruiz, drafted in as a late replacement.

Floored four times by Ruiz before the seventh round stoppage, Joshua can take some hope from history, however.

Heavyweight champions Tyson, Lennox Lewis and Wladimir Klitschko all suffered major title upsets in their careers before coming back strong, even if their images were changed forever.

Tyson's 1990 defeat to James 'Buster' Douglas in Tokyo still ranks as the biggest of them all, while Lewis lost to Oliver McCall in 1994 before a rematch win years later.

Ukrainian Klitschko, beaten by Joshua at London's Wembley Stadium in 2017, lost to Corrie Sanders in 2003 and Lamon Brewster in 2004 before returning to the top.
