WBC heavyweight champion Deontay Wilder (40-0, 39 KOs) believes his his main division rival, Anthony Joshua (20-0, 20 KOs), knows exactly what will happen if they collide in the ring.

Wilder plans to be ringside when Joshua stakes his IBF, IBO, WBA titles against WBO champion Joseph Parker (24-0, 18 KOs) on March 31 at Principality Stadium in Cardiff, Wales.

"I’ve done enough calling Joshua out. How many times do I have to do that? I am the blockage and the end of the line for his career and he knows it. That’s scary for him," Wilder told Premier Boxing Champions.

Wilder was in action two weekends back at Barclays Center in Brooklyn, where he survived near disaster in the seventh round to score a knockout victory over undefeated challenger Luis Ortiz of Cuba.

He believes the win over Ortiz is better than what Joshua accomplished in April 2017, when he got off the floor in the sixth round to knock Wladimir Klitschko in the eleventh round.

“Ortiz was undefeated. Klitschko was already dethroned and coming off of almost a two-year layoff," Wilder said.

Wilder was not impressed with Joshua's last performance - which saw the British puncher have some trouble in putting away mandatory challenger Carlos Takam in the tenth round.

Takam was physically much smaller than Joshua, but have the champion some fits with his style.

Wilder believes that he's been destined to beat Joshua.

When the finally face each other, Wilder expects to break Joshua down and punish him - until Joshua either quits or the towel gets thrown in.

“[Joshua] knows he’s gonna lose one day, and that it’s going to be against me. I know I’m going to knock him out. He’ll show courage until he runs out of gas,” said Wilder.

“Then it’s life and death for him. Once he’s tired, I see him giving up. Once that happens, I’m going to turn up the heat on him and it’s a wrap. They may throw in the towel.”
