Briton Moses Itauma has been ordered by the IBF to hold talks with Cuba's Frank Sanchez about fighting for the vacant heavyweight ****** le.
Last week Oleksandr Usyk relinquished his IBF, WBA 'super' and WBC.
The IBF said that, "in accordance with IBF championship rules", it now wants Sanchez, who is number one in their heavyweight rankings, to fight number three contender Itauma.
It said: "They have until 29 July to reach an agreement."
However, 21-year-old Itauma is scheduled to fight Croatia's Filip Hrgovic at London's O2 Arena on 29 August in what he has called his "toughest fight".
