As an MMA fighter, he formerly competed in the heavyweight division, most of which he fought with Fighting Network RINGS where he was known as Zaza Grom.
He holds notable wins over Volk Han and Travis Fulton, and has fought Bobby Hoffman and Renato Sobral.
He beat Daniel Sánchez (Cuba), Dolgorsürengiin Sumyaabazar (Mongolia) and was defeated in the semis by Leri Khabelov (Russia).
The funny thing was that the entire tournament had to stop because the other two Georgian fighters didn’t even bother to get changed for the fight because they thought Bitsadze would clean house.
However, as they became entangled in the ring ropes, and after the restart Renato took his back, trying an armbar and an inverted triangle choke to no avail.
