Mayol headlines new Guadalajara card

An injury to former unified junior bantamweight titlist Cristian Mijares has forced the cancellation of one Feb. 27 boxing card, but paved the way for another to gain American pay-per-view exposure.

Mijares (38-6-2, 17 KOs), now campaigning at bantamweight, was due to box on the Cancun, Mexico, half of the Integrated Sports-distributed "Double Assault" split-site pay-per-view show. However, Mijares withdrew Tuesday because the broken eardrum he suffered in his sixth-round knockout victory against of B.J. Dolorosa on Dec. 12 has not healed enough for him to fight.

"After looking forward to coming back and restoring his rightful place among the best pound-for-pound fighters in the world, Cristian Mijares was crushed with disappointment to learn a broken eardrum he suffered Dec. 12 hasn't healed properly and doctors wouldn't clear him to fight Feb. 27," said KO Entertainment promoter Ignacio "Nacho" Huizar.

With Mijares injured, the card in Cancun is off, including the match between Hugo Hernan Garay and Chris Henry, who were due to meet for an interim light heavyweight belt.

The Cancun portion of the pay-per-view has been replaced by a card from Guadalajara, Mexico, which will be headlined by the first title defense of junior flyweight titlist Rodel Mayol (26-4-1, 20 KOs) of the Philippines facing former titlist Omar Nino (28-3-1, 11 KOs) of Mexico.

Also featured on that segment of the show: a 10-round lightweight bout between Daniel Estrada (21-1, 17 KOs) and Angel Alirio Rivero (21-7-1, 14 KOs).

The Puerto Rican half of the show remains intact. The pay-per-view will open at Ruben Rodriquez Coliseum in Bayamon as former junior bantamweight titlist Marvin Sonsona (14-0-1, 12 KOs) of the Philippines meets Puerto Rico's Wilfredo Vasquez Jr. (17-0-1, 14 KO's) for a vacant junior featherweight belt.

Sonsona, 19, won a junior bantamweight belt in September by outpointing Puerto Rico's Jose "Carita" Lopez, but was stripped before his first defense in November for failing to make weight. Sonsona fought Alejandro Hernandez to a draw in the nontitle bout and then moved up to junior featherweight.

Vazquez Jr., 25, the son of the former three-division titleholder, has won eight in a row since a draw in 2007 to earn the title bout.

Also featured on the Puerto Rican portion of the card will be cruiserweight Carlos Negron (7-0, 6 KOs), a 2008 Puerto Rican Olympian, and the pro debuts of 2008 Puerto Rican Olympic twins, flyweight McWilliams Arroyo and bantamweight McJoe Arroyo.
