WBC heavyweight world champion Deontay Wilder (39-0, 38 KOs) has reiterated that he doesn't see any way that Joseph Parker will win a decision against Anthony Joshua.

He's advising the New Zealand heavyweight to forget about winning a twelve round decision and focus on securing the knockout.

Joshua (20-0, 20 KOs) and Parker (24-0, 18 KOs) will collide in a highly anticipated unification for the WBA, WBO, IBF, IBO world titles on March 31 at Principality Stadium in Cardiff, Wales.

Wilder is back in the ring on March 3rd, when he makes a voluntary defense against Luis Ortiz at the Barclays Center in Brooklyn, New York.

Should he win, Wilder has already booked a trip to sit ringside with the Sky Sports broadcast team to give his thoughts on the Joshua vs. Parker showdown.

He plans to challenge the winner in the aftermath - which he hopes will be Joshua.

When breaking down the fight, Wilder is still confident that it won't end early. He expects a long contest that enters the late rounds. And he doesn't rule out the possibility of an upset by Parker, but cautions that he doesn't see that happening with a knockout involved.

"I've always said 'later rounds'. I see that fight going later rounds if Joseph Parker is smart in what he does. He has nice movement and is able to execute on all of the opportunities that he sees with Joshua. Because Joshua can't move his head," Wilder said. 

"He's a muscle, body-building type of guy. You've seen my dance? [chuckles] With that, if he's able to calculate what he needs to do in the ring - because the ring has a lot of secrets - if he's able to do things he needs to do, I see late rounds. But, like I said before, I think they're going to have to knock Joshua out because they're not going to give it to him."
