The strawweight title will be up for grabs in next month’s ONE Championship 66 headliner.

Officials today announced a fight between strawweight champion Yoshitaka Naito (12-0) and challenger Alex Silva (6-1).

ONE Championship takes place Dec. 9 at Impact Arena in Bangkok, and it streams as an online pay-per-view in North America following prelims on Facebook.

Naito, a 33-year-old Japanese fighter, is a former Shooto flyweight champion who made his ONE Championship debut in 2016. In his first bout with the promotion, Naito submitted Dejdamrong Sor Amnuaysirichoke for the title. The submission specialist then defended it by tapping out Joshua Pacio. He now returns from a 14-month layoff as he searches for his 13th straight victory.

He meets Silva, a 35-year-old Brazilian who turned pro in 2011 and has spent most of his career with ONE Championship. “Little Rock” is currently riding a five-fight winning streak with the promotion, which included a recent submission victory over Hayato Suzuki (17-1-2) earlier this month.
