Ruiz became the first Mexican heavyweight champion when he stopped Anthony Joshua in the seventh round of a huge upset June of 2019.

Only six months later, Ruiz outboxed over twelve rounds in the Joshua rematch.

Ruiz has been inactive since the loss.

He later hired very respected trainer Eddy Reynoso, who is best known for his work with Saul 'Canelo' Alvarez.

Ruiz is scheduled to face fellow Mexican Chris Arreola in a crossroads showdown on May 1. The contest will headline a Fox Sports pay-per-view card.

During the ongoing camp to prepare for the fight, Ruiz shed a lot of weight - and is absolutely going to be lighter than he was for the rematch with Joshua.

Whyte, who last month got revenge with a stoppage win in his rematch with Alexander Povetkin, views Ruiz-Arreola as a "garbage fight."

"A strategic comeback fight," Whyte told Sky Sports. "It's a fight that's going to make him look good.

"Make him look like, 'Oh yeah, he's this and he's that,' but on paper it's not. If you run it on paper, it's not, because Chris Arreola is shot. Chris Arreola has been shot for a few years.

"If he was fighting Chris Arreola a few years ago, people would be like, 'No, that's a garbage fight.' Now it's the same, if not worse. [Arreola] was a decent fighter in his heyday but he's been retired for two years since losing to Adam Kownacki.

"It's a good strategic move from his team, him coming back and he'll bash Arreola. [People will say] 'Andy Ruiz, yeah he's back, and he's motivated, and he looked so good.' Let's be honest, it's Chris Arreola he's fighting. Typical joke fight from the fake Mexican."
