The WBA has called a purse bid for the heavyweight bout between its regular champion Kubrat Pulev (pictured) and its mandatory challenger Michael Hunter. [The true world champion, Oleksandr Usykm is recognized as the WBA super champion]. The purse bid is scheduled for Tuesday, May 27th in Houston and will be conducted by WBA Championships Committee Vice-Chairman Julio Thyme. After granting both camps a negotiation period that failed to produce a deal, the WBA has moved to the next step in the process. Formal notice was sent through official channels, outlining all terms and conditions of the purse bid procedure. Per WBA rules, the purse split has been set at 75% for Pulev and 25% for Hunter. Pulev captured the WBA's secondary title on December 7th, defeating Mahmoud Charr via unanimous decision in Bulgaria.
