On Sunday, it was confirmed that Anthony Joshua and Joseph Parker would go head-to-head in the ring at the Principality Stadium in Cardiff, Wales on March 31 with Joshua's WBA (Super), IBF, and IBO heavyweight titles and Parker's WBO heavyweight title on the line.

The two undefeated heavyweight champions will face one another in the ring in what should be a very exciting clash, as both fighters have a history of winning their fights by knockout. The British boxer has a 100% KO record as he has knocked out all of his 20 previous opponents, while the New Zealander has a record of 24-0 with 18 KOs.

Parker said during a recent interview with Sky Sports that he's not scared of Joshua and that he's looking forward to putting on a great show in the ring with him in two months time. He also said that he believes there should be just one champion.

The New Zealander said: “I’m not scared of AJ. I know he’s a good fighter and I respect him, but I back myself with anyone I jump in the ring with. I’m looking forward to putting on a great show. I don’t care if I win or lose. I just want a challenge and I think there should be one champion.”

When asked about stating that Joshua has a glass chin, the unbeaten WBO heavyweight champion said that he has a lot of respect for his opponent, but also stated one of them is going to get knocked out when the two clash at the Principality Stadium in Cardiff at the end of March.

Parker said: “I know he’s been down. Glass chin is just one of those things where my team, we came up with to describe him and what his chin is, but I feel like I have a lot of respect for him.

“In the last fight I saw with [Wladimir] Klitschko, he got knocked down, got up and showed a lot of heart, so credit to him. But I think when we come together, we’re both going to throw some big bombs and someone is going to get knocked out.”

While Parker is struggling to envision his fight against Joshua going the distance, the previous three times he has defended the WBO heavyweight title have ended via decision.

We'll have to wait until March 31 to see if this trend will continue or stop with one of the two undefeated boxers being KO'ed for the first time in their professional boxing careers.
