With the two sides unable to reach a deal for their IBF heavyweight title eliminator, Kubrat Pulev and Dillian Whyte are headed to a purse bid on May 10, unless they can come together with a deal before that time.

Pulev (25-1, 13 KO) hasn’t fought in a year, since beating veteran professional opponent Kevin Johnson by decision in Sofia, Bulgaria, on April 28, 2017. He’s won five in a row overall, going back to his lone loss, a 2014 knockout at the hands of Wladimir Klitschko, in what was Pulev’s only world title challenge to date.

Whyte (23-1, 17 KO) has won seven straight since a 2015 loss to Anthony Joshua, including his most recent, a sixth round knockout of previously-unbeaten Lucas Browne. Whyte is eager to get back into the ring with Anthony Joshua, who currently holds the IBF belt, along with the WBA and WBO championships. Whyte also holds the WBC silver title, so he’s right in line for a shot at Deontay Wilder, too, but right now Wilder’s team seems entirely focused on making a full unification bout with Joshua, or at least that’s the talk.
