Dillian Whyte is to fight Alexander Povetkin in the UK in May, Eddie Hearn has confirmed to talkSPORT.
Whyte is the mandatory challenger for the WBC belt, which fellow Brit Tyson Fury won in stunning fashion against Deontay Wilder on Saturday night.
The 31-year-old, whose only professional loss came against Anthony Joshua, is determined to get his world title shot but first faces a tough fight against Povetkin.
“Dillian is going to fight Alexander Povetkin – that will be announced this week,” said Matchroom promoter Hearn.
“We’ve made that fight, we will announce it this week. It will be in May, in the UK. It is another brutal fight for Dillian Whyte.
“He doesn’t stop taking on these tough challenges. He is mandatory [WBC] challenger, he can have a nice easy touch and wait if he wants but he wants to get in there and have a tear up.”
Whyte last fought on the undercard of Anthony Joshua’s rematch with Andy Ruiz Jr in Saudi Arabia in December, winning a unanimous decision over Mariusz Wach.
He has been frustrated in his attempts to secure a world title shot and has no choice but to wait in line until 2021 at the earliest, with Fury and Wilder set for a third fight and the winner then possibly facing Joshua.
“He is the current mandatory challenger for Tyson Fury and he is supposed to fight for the world heavyweight title by February 2021,” said Hearn.
“Worst case scenario for Dillian Whyte is he is the mandatory challenger for Fury vs Joshua, if that fight happens.
“The bigger issue is if these guys mess around for too long, Dillian Whyte might have to fight the winner of Fury against Wilder.
“I’d like them to make sure they do the third fight in the summer, then the winner fights Anthony Joshua and the winner fights Dillian Whyte, the mandatory challenger.”
