Boxer Otto Wallin Vows To Spoil Anthony Joshua-Deontay Wilder Fight In March

Otto Wallin intends to be the 6'5", 230 lb. wrench that screws up Anthony Joshua's (very lucrative) plan to fight Deontay Wilder in March ... flat-out saying the scrap ain't happening!

Walling and Joshua are fighting Saturday in Saudi Arabia ... a stacked card that also includes Wilder vs. Joseph Parker. So, what's Otto's beef?

Well, Anthony and Deontay seem to be assuming they'll not only win this weekend, but also skate through relatively unscathed ... 'cause the heavyweight boxing superstars have agreed to fight each other in March.

TMZ Sports talked to 33-year-old Wallin, who has only 1 career loss, which came against Tyson Fury ... a very competitive fight that was nearly stopped after the Gypsy King suffered a gruesome cut above his eye.

We asked Otto about AJ's decision to sign the Wilder contract.

"I just think it's crazy that they think that fight is gonna happen on March 9th. What is it, 2 and a half months? There is no way that fight's gonna happen, I'll tell you that now. There's no way that fight's gonna happen. Maybe in the future."

Wallin continued ... "I'm gonna beat Joshua. Wilder-Parker, that's not an easy fight. he could get beat, too. Even if both guys could win, they have to come out with no injuries. The time's just too short, it's not gonna happen."

We also talked to Otto about the fight with AJ.

We also talked to Anthony ... who as you might've guessed, sees things a bit differently than Otto. Among the topics we discussed ... were the Wallin fight, the news of the Wilder bout leaking, and the recent success of the UK UFC fighters.

Like AJ, Wilder has his hands full, too, with 6'4" Parker, who is 33-3 (23 KOs) as a pro. Deontay, 43-2-1 (42 KOs), last fought in October 2022 when he dispatched of Robert Helenius inside 1 round.

Wilder and Joshua is a fight that fans have wanted for years ... and Wallin, a normally friendly guy, is in this case looking to spoil the party!
