Promising super-middleweight contender Lester Martinez has been forced to withdraw from Saturday night’s main event versus Pierre Hubert Dibombe at Fresno’s Save Mart Arena due to migraine headaches, ProBox TV CEO Garry Jonas announced Monday.

The 29-year-old Martinez 19-0 (16 KOs) of Guatemala is ranked by three sanctioning bodies, including his No. 3 position by the WBA, and is coming off a fourth-round knockout of Joeshon James March 22 in San Bernardino, California, on another ProBox TV main event.

Cornered by 2023 trainer of the year Brian “BoMac” McIntyre, Martinez is ranked ninth in the WBC super-middleweight rankings, and title-fight eligible in the WBO, as well, while sitting at No. 15.

The migraines struck “during his last week of sparring,” Jonas reports.

“Due to sensitivities regarding a boxer’s health, you cannot take any chances with the migraines, and putting him in the ring under those circumstances would be taking an unnecessary risk to his health,” Jonas said.

“In an abundance of caution, Lester will not fight [Saturday] and will undergo tests with neuro specialists in Miami this week to resolve the problem and clear him to resume boxing. We expect to see Lester back in the ring this fall.”

Saturday’s card will now be headlined by a junior-middleweight tilt pitting Mexico’s Vladimir Hernandez 17-6 (7 KOs) versus Argentina’s Francisco Daniel Veron 14-1-1 (10 KOs).

The show still features a WBC junior-flyweight eliminator pitting Mexico’s Erick Badillo 17-0 (8 KOs) versus Nicaragua’s Gerado Zapata 15-2-1 (5 KOs) in the co-main event.

Other bouts include Japan’s unbeaten bantamweight Katsuma Akitsugi  12-0 (3 KOs) versus Jonas Sultan 19-7 (11 KOs) of the Philippines and unbeaten Mongolian lightweight Tsendbaatar Erdenebat 12-0 (6 KOs) vs. Mexico’s Humberto Galindo 14-3-3 (11 KOs).

Despite the absence of the rugged Martinez, Jonas said, “The benefit of ProBox TV’s deep cards is we can withstand a fight falling out.”

The card will begin at 6 p.m. Eastern/3 p.m. Pacific and conclude by 9:30 p.m. Eastern/6:30 p.m. Pacific, to avoid conflict with the Saturday night DAZN card headlined by Edgar Berlanga-Hamzah Sheeraz and Shakur Stevenson versus William Zepeda in New York.
