The World Boxing Council has revealed that their organization received a communication from Gilberto Ramirez's management, who advised them of his withdrawal from a WBC final light heavyweight eliminator with Marcus Browne - which would have had the WBC's interim-title at stake.
According to the sanctioning body, Ramirez's handlers had asked for an extension to the free negotiations period and then backed out "at the last minute."
Because of the unexpected withdrawal, the purse bid, which was scheduled for tomorrow, has now been cancelled.
Ramirez was last seen in action back in December, when he stopped Alfonso Lopez in the tenth round.
The contest with Lopez was his first ring appearance since April 2019, when he stopped Tommy Karpency in four rounds.
In 2016, Ramirez became the first Mexican boxer to capture a world title at super middleweight when he dominated veteran Arthur Abraham over twelve rounds.
By the end of 2018, he made a decision to vacate the belt and move up in weight.
Ramirez made his light heavyweight debut against Karpency, but then his career was in limbo while he went through issues with his promoter of several years, Top Rank. Eventually Top Rank and Ramirez reached an agreement to part ways.
Ramirez, through his own promotional company, staged the December event with Lopez.
The WBC would then order Ramirez and Browne to face each other for the interim-title - because full champion Artur Beterbiev has been out of action since capturing the world title in October of 2019, when he he knocked out Oleksandr Gvozdyk.
Beterbiev, after numerous delays, will return to the ring on March 20th in a defense against Adam Deines in Moscow, Russia.
For his part, Browne has been away from the ring since a technical decision loss to Jean Pascal in August 2019.
