Clash of champions: Jermell Charlo fights Jeison Rosario September 26

WBC Super Welterweight World Champion Jermell Charlo takes on WBA and IBF 154-pound world champion Jeison Rosario in a blockbuster unification showdown on Saturday, September 26 in part two of a first-ever SHOWTIME PPV boxing doubleheader presented by Premier Boxing Champions.

Houston’s Charlo (33-1, 17 KOs) will face the Dominican Republic’s Rosario (20-1-1, 14 KOs) in just the eighth world title unification fight in the 154-pound division’s history. It is also just the second fight with three super welterweight world title belts up for grabs.

The 30-year-old Charlo regained his title by knocking out Tony Harrison last December and avenging his only career loss. Trained by Derrick James in Dallas, Charlo first captured the title in 2016 with a knockout victory over John Jackson on SHOWTIME. He went on to make three successful title defenses, scoring highlight reel knockouts over Erickson Lubin and Charles Hatley, in addition to a decision victory over Austin Trout in which he dropped the former champion twice.

Rosario captured the WBA and IBF belts at 154-pounds with an upset victory over Julian Williams in January, stopping him in the fifth round. Now training out of Miami, the 25-year-old rode an eight-fight unbeaten streak into the showdown with Williams, including victories over 154-pound contenders Jamontay Clark, Justin DeLoach, Jorge Cota and Marcos Hernandez. He has shown considerable power by either earning a stoppage victory or scoring a knockdown in seven of his last nine contests.

The unprecedented pay-per-view twin bill, in which both Charlo brothers face the toughest tests of their careers, features six compelling fights in all, five of which are world title fights, on the same night for one price. Part one of the SHOWTIME PPV telecast begins live at a special time of 7 p.m. ET/4 p.m. PT.

The first three-fight card is headlined by WBC Middleweight World Champion Jermall Charlo taking on vaunted challenger Sergiy Derevyanchenko in the main event. Following a 30-minute intermission, the second three-fight card, headlined by the historic Charlo vs. Rosario unification matchup, will begin. Unbeaten former champion Luis Nery will battle undefeated Aaron Alameda for the vacant WBC Super Bantamweight World Championship in the co-feature, while former unified champion Danny Román faces off against former champion Juan Carlos Payano in a WBC Super Bantamweight title eliminator bout to open the second installment of the pay-per-view.
