MMA Fighting Share this story The stage has been set for Gordon Ryan’s ONE Championship debut. Ryan, one of the most decorated competitive grapplers of all time, will face MMA legend Shiny Aoki in an “an openweight grappling super match” on Aug. 27, according to an announcement from ONE CEO Chatri Sityodtong on Monday. The rules of this contest are still to be announced, but this will not be the first grappling match that Aoki has been a part of for ONE. He also welcomed Brazilian jiu-jitsu ace Garry Tonon to the promotion in a grappling super match in May 2017, that Tonon won via heel hook. Tonon currently competes as a featherweight in ONE’s MMA division.
