WBC interim-heavyweight champion Alexander Povetkin is hard at work for next month's rematch with Dillian Whyte.
Back in August at Matchroom's Fight Camp in Brentwood, Povetkin scored a brutal fifth round knockout of Whyte.
With the victory, Povetkin picked up the WBC interim-title and derailed Whyte's position as mandatory challenger.
Afterwards, Whyte exercised an immediate rematch clause - with the second fight set down for November 21 in the UK.
Povetkin's trainer is already working on tactics to neutralize Whyte's weapons.
"Everything is going according to plan, we have started sparring work," said his trainer Ivan Kirpa to Sky Sports.
"We are working on a technical solution to neutralize Whyte's short left hook - obviously this is a technique he always does in every fight. The team is in a good working mood. We treat revenge with full dedication and understanding of everything that happens."
Povetkin's promoter Andriy Ryabinskiy denied a recent claim that his boxer was on the verge of being pulled out of the fight after being dropped twice in the fourth round.
"It's nothing more than just rumors," Ryabinskiy told Sky Sports.
"The fourth round wasn't easy, it made us worry, but Sasha felt good, he was not particularly shocked. I think there were usual questions after the knockdown: 'Are you all right? Shall we continue the fight?'"
WBC President Maurico Sulaiman recently advised BoxingScene.com that his organization's world champion, Tyson Fury, is without a mandatory challenger and currently free to pursue a voluntary defense in the fall - against Deontay Wilder or someone else. The WBC is also backing Fury's pursuit of a full division unification in 2021, with IBF, WBA, IBO, WBO heavyweight champion Anthony Joshua.
