While the 35-year-old admitted defeating Khan would be the ideal way to end his 18-year career, he expressed a desire to get back in the ring again.
This prompted Hearn, the head of Matchroom Boxing to try and organise Brook’s next fight, which he hopes will be against Conor Benn.
Benn, son of boxing legend Nigel, impressed last year with wins over veterans Samuel Vargas, Adrian Granados, and Chris Algieri.
The promoter now wants to do business with Brook, one of his former clients, and arrange a fight with one of his current fighters in the form of Benn.
“He’s made a lot of money now with us,” Hearn said of Brook in an interview with IFL.
