WBO super flyweight champion Naoya Inoue and IBF light flyweight champion Akira Yaegashi will defend their belts in a doubleheader on May 8, Ohashi Boxing Gym announced Wednesday.

The 22-year-old Inoue will face top-ranked David Carmona of Mexico in his second title defense at Ariake Colosseum, looking to improve on his perfect 9-0 career record, with eight knockouts.

Carmona has 20 wins (eight KOs) against two defeats and five draws.

"He's got technique and is a tricky opponent to beat, but I want to fight well and floor him in the end," Inoue said.

The 33-year-old Yaegashi conquered his third weight class in December and will make his first title defense at light flyweight. He'll also face a Mexican in 10th-ranked Martin Tecuapetla.

"I want to show everything I've got," said Yaegashi, who is 23-5 (12 KOs) against Tecuapetla at 13-6-3 (10 KOs).
