ANTHONY JOSHUA has been urged to RETIRE from boxing to prevent him from taking any more damage. Joshua was down four times before a brutal right hand ended it all. And boxing legend Barry McGuigan – whose son Shane formerly coached Dubois – reckons a quicker finish is on the cards in a rematch.

McGuigan told Seconds Out: “I genuinely think it happens sooner in the rematch if Anthony has a rematch with Dubois.

“I think Dubious will knock him out earlier in the fight.”

Joshua, 35, looked set to rematch Dubois, 27, with a date in February in Saudi Arabia already pencilled in.

But his promoter Eddie Hearn has since revealed AJ is dealing with injuries from the first bout which threatens to scupper their rematch.

Instead, Joshua could look to return by May and will consider waiting to fight Tyson Fury, 36, who rematches Oleksandr Usyk, 37, on December 21.

But former featherweight world champion McGuigan urged AJ to hang up his gloves and enjoy the fruits of his labour.

He said: “Anthony is an incredible fighter, he’s had incredible success. I think he should get out with his faculties intact.

“He doesn’t need to fight any more, he can retire and have a lovely life.

“He’s doing himself an injustice by fighting again. There is only one fighter on the way up, and one on the way down.

“Dubois is a very dangerous fighter and he’s only getting better.”
