London, October 10: Anthony Joshua triggered a rematch clause against Oleksandr Usyk for the heavyweight championship, promoter Eddie Hearn confirmed.
Joshua was dethroned by Usyk, who was crowned WBA, WBO and IBF champion after a unanimous points decision victory at Tottenham Hotspur Stadium in London on September 25.
Now 24-2, having also suffered a shock defeat to Andy Ruiz Jr. in 2019 before winning their rematch, Joshua is set to step into the ring again with Usyk next year.
"Joshua is training now, and today we officially triggered the rematch for the Oleksandr Usyk fight, which we will see early next spring," Hearn told DAZN.
"So back in the game and looking for him to become a three-time heavyweight champion."

Joshua had been tipped for a long-awaited duel with Tyson Fury next year before his upset at the hands of Ukrainian opponent Usyk.
Fury is due to face Deontay Wilder in Las Vegas on Saturday as they conclude a contentious trilogy – the former won the second bout following a draw.
"As I said, I'll fight Tyson Fury, Wilder, without the belts. The belts are fun. It's great, it's legacy. But with or without the belts, I'll fight whoever," Joshua said after his loss to Usyk.
"The road to undisputed is a nice title to have and a nice title to chase.
"But would you still watch it, without the belts? That's the main thing – is you've got two competitive fighters in the ring from UK soil, that just want to go toe-to-toe."
