Joseph Parker, who fought WBO, IBF, WBA, IBO heavyweight champion Anthony Joshua in early 2018, is hoping unbeaten Jarrell Miller can pull off a big upset on June 1.

Miller will challenge Joshua at New York's Madison Square Garden. The contest will be Joshua's American debut.

Parker, who held the WBO world title, lost a twelve round decision to Joshua in their unification bout. He's still the only boxer to last the full twelve round distance with the unified champ.

For over a year, Miller has been verbally assaulting Joshua at every turn.

They nearly came to blows last year, when Miller confronted Joshua at a press conference in New York City.

Last month, the scene repeated itself last month when Miller pushed Joshua at their kickoff presser to officially announce their showdown.

"Boxing antics, and things happen all the time, and you've just got to take it how it is," Parker told Sky Sports.

"I'm good friends with Miller, so it's one of those fights where I hope it goes well, and I hope he can pull it off, but it's going to be a hard task, because Joshua is a champion. I'm just going to be interested as a heavyweight boxer and a fan of the sport. I think he got under his skin. Miller is just playing the game, doing what he has to do. It's just one of those things where it's interesting for boxing.

"[Me and Miller] get along well, we message each other, and I'm supporting him because he supported me when I had the Joshua fight. Both fighters are great fighters, and very respectful. It's going to be good to see them matched in the ring.

"Yeah, I'll be supporting Miller. We'll fight anyone. I've got a lot of respect for Tyson and he is the man. But it comes down to boxing, and if I want to be the best, I have to fight the best. I consider him one of the best in my generation as a heavyweight. Listen, I'll fight him."
