Anthony Joshua-Wladimir Klitschko heavyweight title fight set for April 29 at Wembley

With Anthony Joshua's tune-up fight in the rearview, a mega fight awaits.

The IBF heavyweight champion will meet former champ Wladimir Klitschko on April 29 at Wembley Stadium in London, promoter Eddie Hearn announced Saturday after Joshua knocked out Eric Molina.

"We are moving into a huge arena," Joshua (18-0, 18 KOs). "He's a very respectful man outside of the ring, and he's very competitive in the ring. This is the step up people have wanted. Klitschko wants his belts back and may the best man win."

The fight shapes up as a classic crossroads bout: the aging, ex-champion, squaring off against the chiseled man believed to be the present and future of the long-dorman division.

What is less clear is which television network will broadcast the fight - which will also be for the vacant WBA title - in America. Joshua signed an exclusive deal with Showtime earlier this year, who will broadcast his third fight in 2016 this weekend.

Klitschko's three-fight deal with HBO expired, but he's long been one of the network's marquee fighters.

Klitschko has never fought in a stadium like this, though. Wembley holds 90,000 fans, and for a change, Klitschko would be the one on enemy territory.

Joshua, an Olympic gold medalist, broke out this year and is already a pay-per-view star in England. He won the heavyweight title on Showtime with a second-round knockout of Charles Martin in April.

The 27-year-old made easy work of Dominic Breazeale two months later, but now the marquee fight awaits him.

"He is the best man in the heavyweight division and his record speaks for itself," Klitschko said. "This is the fight that the fans want and that is why this fight will happen.

"Do you want to see a big fight? Do you want to see a fight where two Olympic champs are involved? Do you want to see the fight between A.J. and W.K.? You got it."

Klitschko is the dominant heavyweight of this era. He held a version of the heavyweight title for a decade and reeled off a winning streak that lasted 11-plus years before losing to Tyson Fury last November.

The Ukrainian (also an Olympic gold medalist) was scheduled to fight Fury in a rematch on two separate occasions this year, but the Brit ended up in rehab after testing positive for cocaine.

Klitschko (64-4, 53 KOs) will be 41 on fight night and, of course, activity will be an issue after a 17-month layoff.

He'll be facing a younger, fresher, stronger fighter who has all the confidence in the world.

Finally, the sporting world might just get another great heavyweight title fight.
