Valdez (22-0, 19 KOs), from Nogales, México, and who represented México in the 2008 and 2012 Olympics, was the first Méxican fighter to qualify for two Olympic games.  He is considered one of the bright lights of the featherweight division and a new face for boxing's next generation.  He will be making the third defense of the world title he won on July 23, 2016 via a second-round knockout of undefeated No. 2 rated Matías Rueda.  Rueda entered that fight having won his previous 10 bouts by stoppage.  In his first defense, which took place, on November 5, he blasted out No. 1 contender Hiroshige Osawa via a seventh-round TKO.  In his 2017 debut, his first pay-per-view event that featured him in the main event, Valdez, 26, went toe-to toe for 12 rounds with No. 1 contender Miguel Marriaga, winning a unanimous decision.  Marriaga, a three-time world title challenger, went into that fight having won 15 of his previous 19 bouts by way of knockout.

Servania (29-0, 12 KOs), who hails from Bacolod City, Philippines and fights out of Kanazawa, Japan, will be making his U.S. debut.  Known for his aggressive style and good skills and movement, Servania is always in top condition.  He returns to the ring in his first bid for a world title fresh from a second-round TKO victory of Ralph Lulu on April 29, for the vacant WBO Asia Pacific featherweight title.  He is currently world-rated No. 4 by the WBO and No. 7 by the IBF.

Ramírez (35-0, 24 KOs), a two-fisted super middleweight wrecking machine who hails from Mazatlán, México, made history in the co-main event to the Manny Pacquiao vs. Timothy Bradley welterweight pay-per-view on April 9, 2016, when he became México's first fighter to win a super middleweight world title.  Entering the fight as the top world-rated contender, Ramirez gave a virtuoso performance over the defending WBO champion Arthur  Abraham.  All three judges scored it as a 120-108 blitzkrieg.  "I took him to Méxican boxing school," a jubilant Ramírez boasted as he put on the world championship belt .  A sensational young champion, Ramírez, 26, had been scheduled to make his first title defense in July 2016, but a training camp injury to his right hand followed by surgery and rest sidelined him for the remainder of the year.  He returned to on April 22, winning a unanimous decision over Top-10 contender and one-time world title challenger Max "Tiger" Bursak.

Hart (22-0, 18 KOs), the son of Philadelphia boxing legend Eugene "Cyclone" Hart, has transformed from a sensational prospect into a hot contender.  Trained by his father, the highly-rated middleweight contender of the late '60s and early '70s, the younger Hart, at age 28, enters this fight having won nine of his last 10 bouts by way of knockout.  He captured the NABO and USBA super middleweight titles in 2015, knocking out Mike Jimenez in the sixth-round.  He successfully defended those titles four times during his two-year reign, including a fifth-round stoppage of Alan Campa on April 8, en route to his No. 1 world ranking  by the WBO.
