The fight at London’s Copper Box Arena will be Bentley’s first since signing a promotional deal with Zuffa Boxing, but comes just days after being stripped of WBO middleweight honors.

On April 4, Bentley (22-3-1, 18 KOs) beat Venezuela’s Endry Saavedra to become the WBO interim champion. In July, he was elevated when Janibek Alimkhanuly vacated his full title and moved up to super middleweight. 

The WBO then ordered Bentley to immediately defend his title against mandatory challenger Yoenli Hernandez and Warriors Boxing won with a $200,000 purse bid offer in late September.

Bentley maintained a willingness to fight Hernandez, but had his appeal for a voluntary title defense rejected. In different circumstances, Mosley Jr. (23-5, 13 KOs) would have been considered a perfectly acceptable challenger.

He sits No. 6 in the WBO rankings and is also No. 2 with the WBA and No. 9 in the WBC's latest rankings update.

On May 10, the 35-year-old American scored an eye-catching sixth-round stoppage of Serhii Bohachuk. Bentley hasn’t let anything outside the ring distract him from a serious challenge. 

“I think he [Mosley] is a dog, man. I think he's good,” he told Sky Sports. 

“He loves a scrap. You hit him, and he just wants to keep coming forward. He's obviously not as skillful as his dad, but he's got that heart and grit. That’s probably just in their blood. He doesn't quit. He's been in some tough fights, and I feel like we've got a similar journey. We've always taken tough fights and come through some; we haven't come through some. I think we're going to be in a good fight because we're kind of cut from the same cloth.”

Slowly but surely, the middleweight division seems to be getting closer to the clarity it's needed for some time, and Bentley hopes to capitalize. 

Last month, WBC champion Carlos Adames (25-1-1, 18 KOs), had joined Bentley and IBF titleholder Aaron McKenna (21-0, 10 KOs), as part of the Zuffa stable.

Bentley welcomed Adames’ arrival and hopes it leads to a series of major fights in 2027. 

“Yeah, most definitely, man. Those are the fights that I want,” he said.

“When I saw him sign, I think I was probably happier than I should have been. He obviously has his first fight coming up soon, then he's gotta fight his mandatory, I think, and then that's the fight we can get on next year.

“I think when I first became champion, I reached out to him on Twitter saying, "Let's unify, champ." And he was like, "Yeah, let's go." Obviously, at the time we were both with our promoters, so it was hard to kind of put our heads together and get the fight on, but now we're both under the same banner, it should be easy, man.”
