Heavyweight boxing champ Tyson Fury has voluntarily vacated his WBO, WBA and IBO titles so he can "fully focus on his medical treatment and recovery" ... so says a rep for the fighter.
In a statement issued by Fury's marketing team, Hennessy Sports -- they never mention cocaine specifically ... but they do make reference to a "serious medical condition."
"[Vacating the belts] will also allow him the time and space to fully recover from his present condition without any undue pressure and with the expert medical attention he requires and his close family support."
Fury failed two drug tests leading up to his fight with Wladimir Klitschko -- both tested positive for cocaine -- and Fury later admitted he's had a ton of blow over the years.
"I feel that it is only fair and right and for the good of boxing to keep the titles active and allow the other contenders to fight for the vacant belts that I proudly won and held as the undefeated heavyweight champion of the world when I defeated the long-standing champion Wladimir Klitschko," Tyson said in the statement.
"I now enter another big challenge in my life which I know, like against Klitschko, I will conquer."
