Britain's Anthony Joshua retained his International Boxing Federation, World Boxing Association and World Boxing Organisation heavyweight titles with a seventh-round stoppage of Alexander Povetkin at London's Wembley Stadium on Saturday.
However, his plan to become the undisputed world heavyweight champion may have to wait a little longer as WBC titleholder Deontay Wilder announced earlier on Saturday a showdown with Joshua's compatriot and former world champion Tyson Fury on December 1 in the United States. "I look back at the feedback of people who support me and my critics on where I need to improve again". "Every jab takes a breath out of you and I slowed him down".
As for Fury's chances against Wilder, Joshua said: "He knows how to spoil a fight".
Joshua appeared to be in control in the opener, but Povetkin caught Joshua with a sweet three punch combo at the end of the round.
Dillian Whyte and Oleksandr Usyk have also been mentioned as possible opponents for Joshua. There's no mention of Tyson Fury, the lineal heavyweight champion of the world.
It was a close contest, but the young Brit ultimately prevailed, extending his unbeaten professional record to 22 wins from 22 fights, with 21 knockouts.

The probe will also release a French-German landing vehicle named Mobile Asteroid Surface Scout (Mascot) for surface observation. The cautious announcement came after a similar JAXA probe in 2005 released a rover which failed to reach its target asteroid.
BBC Sport boxing correspondent Mike Costello: "13 April back at Wembley is an absolute definite". Two failed doping tests in 2016 cost Povetkin a crack at Wilder, but he looked risky when he knocked out Joshua's fellow Briton David Price in March.
A powerful right hand sent the Russian backwards, and two lefts and a further right secured the first, heavy knockdown from which he did well to return to his feet. I don't think Joshua was hurt or stung at all and that's an achievement. "He was moving great, throwing different shots, so it was controlled and he didn't waste anything". Povetkin previously fought Klitschko for the unified titles, but was unsuccessful.
Paul Hayward, The Daily Telegraph: "These 80,000 sell-outs have become a blessing and a burden for Joshua". And everything to lose.
Fury's promoter Frank Warren refused to confirm whether there was a rematch clause in the contract with Wilder, with Hearn, whose son Eddie promotes Joshua, consequently saying: "There has to be a rematch clause".
Oliver Holt, Daily Mail: "Joshua showed once more that he is the real deal". After that loss, Povetkin won eight straight fights with six of those wins coming by knockout. "Only the most parsimonious will deny him the credit he deserves now". That is a hard choice to make, even for world champions, when you're exhausted and you're hurt and you know there's more to come.
