Anthony Joshua is "more confident" than ever and has signed the paperwork for his rematch with Oleksandr Usyk, according to the Briton's promoter Eddie Hearn.
Usyk dominated Joshua to claim the WBA Super, WBO and IBF titles at Tottenham Hotspur Stadium last September, condemning the 32-year-old to a second professional defeat.
Joshua activated his rematch clause but plans for a second bout were thrown into doubt after Usyk returned to Ukraine to defend his homeland following the Russian invasion.
However, Usyk has started preparing for the rematch in April, with the bout set to take place in Saudi Arabia, with the Ukrainian's promoter Oleksandr Krasyuk suggesting the clash will take place in August.
After a lengthy delay for confirmation of the fight, Hearn said on Saturday that the paperwork for the clash has been signed and a formal announcement will come next week.
"This fight is on and you will get an official announcement early next week," Hearn told BBC Radio 5 Live.
"[AJ] understands that in a fight of this magnitude, things do take time. It's taken time but we're in a great place. He's been training throughout, so has Oleksandr Usyk.
"AJ is more confident than I've ever seen him going into a fight. We believe he's going to win the fight."
