Heavyweight contender Luis Ortiz is tabbing WBC champion Deontay Wilder to pull off an early knockout victory over IBF, IBO, WBA, WBO world champion Anthony Joshua.

Ortiz (28-1, 24 KOs) is scheduled to meet Razvan Cojanu (16-3, 9 KOs) on July 28 in a 10-round bout that is the co-feature of a Showtime-televised card (10 p.m. ET/7 p.m. PT) at Staples Center in Los Angeles.

In Ortiz's last fight, he nearly derailed Wilder (40-0, 39 KOs) in the seventh round when he badly hurt the champion - but Wilder recovered and dropped Ortiz twice in the tenth round for a knockout victory.

Wilder and Joshua were in talks to fight each other in the fall, but the negotiations fell apart.

Joshua will now face mandatory challenger Alexander Povetkin on September 22nd at Wembley in London.

But Joshua has his next fight date set, for April 13 at Wembley, and he's hoping to get Wilder in place for that date - provided everything goes well in the Povetkin fight.

After feeling the power of Wilder, Ortiz believes that his former foe would crush Joshua in three rounds.

“Wilder would knock out Joshua in three rounds,” said Ortiz to Premier Boxing Champions. “Wilder’s the faster and more aggressive of the two fighters. Of the two fighters, Wilder probably has the better chin. Joshua will not be able to withstand Wilder’s punching power.”

“Wladimir Klitschko put Joshua on his [butt], and a younger Wladimir would have gotten him outta there. Wilder will not forget what Klitschko did to Joshua, so I see Wilder being all over him and Joshua hitting the floor. Joshua will have no answer for Wilder’s style, which is a crazy powerful approach coupled with his chin.

“With all of that being said, Wilder is the superior fighter. Joshua will not be able to withstand his punches at all, point-blank, period.”
