Anthony Joshua vs Alexander Povetkin: Eddie Hearn ‘nervous’ ahead of one of Joshua's toughest fights to date

Wiladimir Klitschlko is the only person to beat Povetkin, who could be Joshua's toughest opponent to date

Promoter Eddie Hearn says he is "nervous" about Anthony Joshua's showdown with Alexander Povetkin at Wembley on Saturday.

Joshua, the WBA, WBO and IBF world heavyweight champion, faces 39-year-old Russian Povetkin, who has only been beaten once in his 35-fight career - by Wladimir Klitschko in 2013.

"It's a massive show, a massive event with the biggest star in world boxing and the best heavyweight in the world," Hearn said.

"But I'm a bit nervous because I think this is a much tougher fight than people give it credit for. Boxing fans know how big a fight this is and how tough a fight this is.

"Outside of Klitschko I think on paper this is the toughest fight of Joshua's career so far.

"He's expected to win. But Povetkin punches very hard, he's got a good chin, he's durable. I expect this to be a real test."
