Nigerian-born British heavyweight champion Anthony Joshua will face WBA mandatory challenger Alexander Povetkin at the Wembley Stadium on September 22.

The WBA, IBF and WBO champion will defend his titles against Povetkin, who was WBA champion from 2011-2013.

Joshua, 28, had earlier unified the three aforementioned belts through a unanimous points victory over Joseph Parker of New Zealand at the Principality Stadium, Cardiff in March.

38-year-old Russian Povetkin was on the Joshua-Parker undercard and he knocked out David Price in their clash.

The September 22 duel will be a fight between two former Olympic champions.

Povetkin won gold medal in the super-heavyweight category at the 2004 Olympic Games in Athens, while Joshua repeated the feat in the same category at the 2012 Olympic Games in London.

The British boxer will go into September’s fight on the back of 21 professional bouts without defeat.

On the other hand, Povetkin has suffered just one defeat since he started his professional career in 2005 and it came in 2013 when he lost his fight with retired Ukrainian boxer Wladimir Klitschko in Moscow by unanimous decision.
