Anthony Joshua can unify the division against WBC champion Deontay Wilder

Anthony Joshua faces Alexander Povetkin in what the British champion has described as the "second hardest fight" of his professional career.​ Povetkin, the mandatory challenger to the WBA title, has the potential to become Russia's first ever unified world heavyweight champion, with Joshua's IBF, WBO and IBO straps on the line too.

The 39-year-old has lost just one of his 35 fights, a points defeat to the great Wladimir Klitschko in October 2013. Since then he has won eight consecutive fights, including a knockout victory over David Price on the Joshua-Parker undercard. Ominously, he has never been stopped.

Meanwhile, Joshua will be looking to extend his flawless professional record to 22-0 in his third fight at Wembley.
