A May 31 Premier Boxing Champions (PBC) show designed to match the main event and co-feature winners has now become a quadrupleheader.

Two more fights will bolster the already announced PBC on Prime Video show from Michelob ULTRA Arena in Las Vegas. Yoenli Hernandez and Kyrone Davis will meet in a crossroads middleweight scrap, while unbeaten junior middleweights Isaac Lucero and Omar Valenzuela will open the four-fight live stream. 

The bouts will accompany the previously announced Caleb Plant-Armando Resendiz and Jermall Charlo-Thomas “Cornflake” LaManna super middleweight contests. Wins by both Plant, 23-2 (14 KOs), and Charlo, 33-0 (22 KOs), are expected to lead to a collision between the two later this year.

There is no guarantee of a grander next assignment for the pair of well-matched bouts added to the show. 

Cuba’s Hernandez, 7-0 (7 KOs), now based in Providence, Rhode Island, has yet to be extended the distance or beyond the eighth round in his three-year pro journey. In fact, he has barely lost a round in any of his seven pro fights, but he expects – and hopes for – a stiffer challenge in May.

“We’re training very hard to face a difficult fighter in Kyrone Davis,” said Hernandez. “We have to adjust to his style and do everything that we can to come out with the victory on May 31. After this win, I’m ready for everyone at 160 or 168 pounds.

“Don’t miss this fight, because I’m here to change the narrative that Cuban fighters can’t be exciting world champions.”

Davis enjoyed an interesting career U-turn in recent months.

A 30-year-old Delaware-based contender, Davis was on course to face Italy’s Etinosa Oliha in an IBF title eliminator. Those plans drastically changed when a decision was made to not travel to his opponent’s home country for the modest payday that accompanied the assignment.

Furthermore, Davis abruptly announced his retirement from boxing in the aftermath.

As with all boxing exits, he walked back that claim once the opportunity arose to appear on this show. Guided by the capable Stephen “Breadman” Edwards – who also trains Plant – Davis is all the way back in a boxing state of mind. 

“Everything in training camp is going as planned,” insisted Davis, who has won three straight. “I can’t wait to get back in the ring on May 31. I’m very confident in getting another win against a strong, good fighter. I can guarantee action and I really think our fight may steal the show.”

Davis will fight for the first time since a career-best win over then-unbeaten Elijah Garcia. The bout came in support of the June 15 Gervonta Davis-Frank Martin PBC on Prime Pay-Per-View event from MGM Grand Garden Arena in Las Vegas. 

Opening the show, Tijuana’s Lucero, 16-0 (12 KOs), returns to the US for the first time since his 2019 pro debut.

Lucero, a 26-year-old prospect, is riding a five-fight knockout streak headed into his toughest matchup to date. He enters the equation well-equipped, with trainer Bob Santos in his corner and promoter Sampson Lewkowicz guiding his career.  

“I’m very thankful to my team for believing in me and helping me land this important opportunity,” said Lucero. “Being in Las Vegas to train has brought the best out of me, and I feel like everything is coming together at the perfect time. I’m working with one of the best trainers in boxing in Bob Santos, and his whole team.

“I know I need to be at my best because this is a very important step in my journey to the world title.”

The same dream is shared by his opponent and fellow Tijuana native. 

Valenzuela will be making his US debut against Lucero. A 28-year-old knockout artist, Valenzuela has stopped each of his plast eight opponents – though none of them rate anywhere close to Lucero’s level.

Then again, the reason for taking this fight was to prove to the world – and himself – that he belongs at this level. 

“I am very grateful for this opportunity to begin building my name against a quality opponent on a big stage,” said Valenzuela. “Lucero seems to be getting a lot of attention, but we’re both undefeated, so I’m excited to punch the freckles off his face.

“After this fight, they will be saying that I’m the next great fighter coming out of Mexico.”
