WBO super flyweight champion Naoya Inoue and Akira Yaegashi, a former champion in two weight divisions, will fight on Dec. 29 in a world title bout doubleheader, their Ohashi Gym announced Tuesday.

Inoue will be fighting for the first time since last December, when he became the first Japanese fighter to win two world titles in just eight fights. He injured his right hand in the process.

"I'm 1 percent anxious, and 99 percent excited," Inoue said of his bout at Ariake Colosseum against top-ranked contender Warlito Parrenas of the Philippines.

The 22-year-old Inoue is 8-0, including seven knockouts.

The 32-year-old Parrenas, who has fought in Japan under the name Wars Katsumata, is 24-6-1 (21 knockouts).

Yaegashi, 32, will take on 24-year-old IBF light flyweight champ Javier Mendoza of Mexico. Last December, Yaegashi failed in his attempt to win his third world title.

"I didn't think I'd have another shot at a world title this soon," said Yaegashi, whose record stands at 22-5 (12 KOs).

Mendoza, who will be making his second title defense, is 24-2-2 (19 KOs).
