yea. back in the day. beat chris leninger and tito ortiz in the same night.
but thats the only fights sherdog has on him in the ufc. other than that pancrase back in the day and pride.
is he related to ken and frank?
I'm pretty sure that Tito Ortiz beat him. As far as I know there is no relation between them.
www.FightFinder.com says that tito won by TKO.
