Briton Dillian Whyte will have the chance to get his revenge against Alexander Povetkin as Matchroom Boxing confirmed their rematch for 6 March.
The Russian, 41, produced a stunning knockout win in the fifth-round of their WBC interim title bout in August.
Whyte, 32, was originally set to meet Povetkin for a second time in late November 2020 at Wembley Arena.
However, the fight was postponed after the the veteran Russian tested positive for Covid-19.
"This is the fight of my career - the fight of my life," said Whyte.
"I was ready to go in November. I can quickly accept defeat and a setback. I'm very adaptable. For me it was a loss, but I did a lot of good things.
"It was a good fight [in August]. I think back on it, I should have jumped at him earlier. I let him back into the fight."
Povetkin said he "felt great" having recovered from coronavirus and said he wanted another shot at a world title fight.
Campbell Hatton, 19, son of ex-world champion Ricky Hatton, will make his professional debut on the same card.
Promoters Matchroom also announced that Leeds fighter Josh Warrington will defend his IBF featherweight title against Mexican Mauricio Lara on 13 February.
Warrington, 30, has not fought since October 2019 when he stopped Sofiane Takoucht in two rounds in the third defence of his belt. He was supposed to fight WBA champion Xu Can, but the Briton is now adamant the Chinese boxer does not want to face him and then challenged American WBC champion Gary Russell to a contest.
Warrington also said he was excited about his forthcoming fight and was glad to be back in the ring.
"This is meant to be the peak of my career - my golden years," he said. "Nobody could do anything about the pandemic - it came out of the blue."
