Shawn Porter could fight Paulie Malignaggi before Kell Brook

Both men must confirm in writing that whomever emerges as champion has the obligation to face Brook next.

Porter-Malignaggi must take place by April 19, with the winner required to face Brook 90 days thereafter.

If Porter-Malignaggi fails to materialise by April 19, Porter’s next defence must be against the unbeaten Sheffield star. Brook’s promoter Eddie Hearn explained the findings as Brook prepares to face Alvaro Robles in a ten-round clash at the Echo Arena in Liverpool on Saturday, live on Sky Sports.

“The IBF wrote to me last week to confirm that IBF champion Shawn Porter had asked for an exemption to fight Paul Malignaggi on April 19, 12 days outside of the restricted period,” said Hearn.

“We asked that if the exemption be granted then it should be accompanied by certain requirements, the most important of those being that both fighters in the proposed April 19 bout must agree in writing to face Kell within 90 days of the bout or by July 19.

“We received confirmation from the IBF today that the exemption would only be granted under a number of conditions including the above.

It is great news for Kell after a frustrating period, and he just has to take care of business on Saturday night then I am sure Britain will have another World champion by July 19.”
