Jose Ramirez will fight Rances Barthelemy on April 27 in Fresno, California, and Vergil Ortiz Jr. will meet Thomas Dulorme in the DAZN co-feature, sources told ESPN on Sunday.
The event will mark Ramirez's Golden Boy debut after the former junior welterweight champion parted ways with longtime promoter Top Rank.
Ramirez (28-1, 18 KOs) is ESPN's No. 7 boxer at 140 pounds. The Olympian made four successful title defenses and unified belts before he dropped a decision to Josh Taylor in an undisputed championship fight in May 2021.
Ramirez, 31, has competed just twice since his lone pro defeat. Most recently, he scored an 11th-round KO of Richard Commey in March 2023. The fight against Barthelemy will be Ramirez's 11th in his native Fresno, including his past two bouts.
Barthelemy (30-2-1, 15 KOs) is a former two-division champion. The 37-year-old Cuban fighter had title reigns at 130 and 135 pounds but hasn't competed in a title bout since a 2018 decision loss to Kiryl Relikh.
Barthelemy last competed in May, a majority-decision win over Omar Juarez. That performance followed a sixth-round TKO loss to Gary Antuanne Russell in July 2022.
Ortiz (20-0, 20 KOs) is ESPN's No. 7 junior middleweight. The 25-year-old from Dallas is coming off a first-round TKO win over Fredrick Lawson in January, a bout that snapped a 17-month layoff. The bout was Ortiz's first at 154 pounds.
Since March 2022, Ortiz has withdrawn from three fights due to health issues related to rhabdomyolysis, a condition that occurs when damaged muscle tissue releases its proteins and electrolytes into the blood. Ortiz was rated No. 3 by ESPN at 147 pounds when he was set to meet Eimantas Stanionis last year. That bout was postponed three times; first after Stanionis underwent an emergency appendectomy and then twice due to Ortiz's rhabdomyolysis recurrence.
Now that Ortiz is set to fight for the second time in four months, the power puncher could challenge for his first world title later this year. Ortiz is the No. 1 contender to the WBA title held by Israil Madrimov.
Dulorme (26-6-1, 17 KOs) had suffered three consecutive defeats, including a first-round KO loss to rising star Jaron Ennis in October 2021, before recovering in a third-round TKO win over Abraham Peralta in July 2022.
Overall, Dulorme has won only two of his past seven bouts. The 34-year-old Puerto Rican fighter will enter the ring on the heels of a career-long 21-month layoff.
Also on the card, two-division champion Joseph "JoJo" Diaz (33-5-1, 15 KOs) will take on Oscar Duarte (26-2-1, 21 KOs) in a 10-round lightweight bout.
