Orzubek Nazarov

Does anyone remember or ever heard of Orzubek Nazarov?
He was lightwheight WBA champion from October 1993 until May 1998 when he lost to Jean Baptiste Mendy, it was his first and last loss, he had quit after that.
Has anyone seen his fights? Any comments? Why he retired after first loss (by UD) at age of 32?

That's a question I been trying to answer for years. I have no idea why he retired. I saw his wins over Joey Gamache and Leevander Johnson. He was very immpressive. The Mendy lost was an upset, but I always figuered he would knock him out in the rematch. But he never fought again.
