Britain’s Anthony Joshua has triggered his clause for a rematch against heavyweight rival Oleksandr Usyk and the fight could take place in March, Joshua’s promoter Eddie Hearn said.

Joshua lost his WBA, WBO, IBF and IBO belts to Ukraine’s Usyk on a unanimous points decision at London’s Tottenham Hotspur Stadium last month.

“He (Joshua) has got his head back in the game,” Hearn told DAZN on Saturday. “He is training now and today we officially triggered the rematch for the Oleksandr Usyk fight, which we will see early next spring.

‘I’ve learnt my lesson’, says Anthony Joshua after Usyk defeat

“We’re looking for him to become a three-time heavyweight world champion. I think realistically March is when you’re likely to see the rematch.”
