Datsik attained some degree of fame in the mixed martial arts community, due mostly to his dramatic knock-out of future Ultimate Fighting Championship heavyweight champion Andrei Arlovski at the MFC World Championship in 1999, and in part to his wild fighting style and notorious in-ring antics.
After losing six straight fights between December 2001 and February 2003, Datsik seemingly disappeared completely, leading to widespread rumors that he had died in a train wreck. These rumors however were set to rest, when it was reported he was alive and well, after being detained for his part in the robbery of various mobile phone shops in St. Petersburg.
