Back in March, Anthony Joshua was forced to go the full twelve round distance for the very first time in his career.
Prior to that fight, Joshua had knocked out all 20 of his opponents within eleven rounds.
At the Principality Stadium in Cardiff, Joshua unified the WBA, WBO, IBF, IBO world titles with a unanimous decision over Joseph Parker.
On Thursday, it was officially announced that Parker would return to the UK on July 28th - when he faces Dillian Whyte at the O2 Arena in London.
Whyte gave Joshua one of his toughest fights back in December of 2015.
He rocked Joshua early on, but eventually saw himself gets stopped in the seventh round.
One would think that Joshua would back the man who took him the distance - but the Olympic gold medal winner believes Whyte will not only come out on top - he expects him to win by knockout. Joshua views Whyte as the bigger puncher and feels that he has more hunger to win.
"Very, very, very good fight," Joshua exclusively told Sky Sports. "If you ask who I'm backing, I'm going with Dillian, and I'm going by knockout as well.
"I feel like Dillian ain't got nothing to lose. He's been screaming out world champions, saying he wants to fight here, he wants to fight there, and I feel like he wants to prove himself.
"Parker is strong, Parker can take a shot, but I feel like in my fight, he was on the back foot and I boxed clever, because I'm trying to set up the big fight with Wilder, so I wanted to box clever, so I could secure the next one, without taking no risks.
"But I feel like Dillian has got nothing to lose, everything to gain. He's going to go in there guns blazing and try and knockout Parker ASAP, secure the win, and get that world title shot."
