A former 1991 World Open Karate Championship finalist who was eliminated by
Andy Hug, Bitsadze trained for his
mixed martial arts debut in his
Fighting Network RINGS's RINGS Georgia team, taking in both editions of the King of Kings tournament. He was pitted against RINGS Holland exponent
Gilbert Yvel at the first one, but he was taken down and submitted via armbar, thus being eliminated from the league. Tariel performed better at the next edition, threatening Renato Sobral with a close
guillotine choke attempt, but being eventually caught in an armbar again and eliminated. ==Mixed martial arts record==
