Brazilian submission ace Leandro Issa and South Korean prospect Soo Chul Kim will battle for the inaugural ONE FC bantamweight title at ONE FC: Rise of Kings, sources close to the event told MMAFighting.com.

Issa and Kim fought once before, with Issa taking the hard-fought unanimous decision at ONE FC's debut event last year.

Since then, Issa (10-2), an accomplished grappler training out of Singapore's Evolve MMA, defeated leglock specialist Masakazu Imanari via unanimous decision to stretch his current winning streak to seven straight.

The 20-year-old Kim (6-4), meanwhile, rides into the title bout after defeating Sengoku veteran Shoko Sato and URCC champion Kevin Belingon in consecutive bouts.

ONE FC 6 takes place October 6, 2012 at the Singapore Indoor Stadium in Kallang, Singapore. Two additional title bouts are planned for the event, which is headlined by a lightweight match pitting former DREAM champion Shinya Aoki against France's Arnaud Lepont.
