British welterweight Kell Brook has warned Amir Khan that he is prepared to move on to bigger things unless he agrees to face him in the near future.
In April, Brook offered Khan the opportunity to fight for his IBF title but the former Olympic silver medallist was unavailable, and although the unbeaten Sheffield fighter is keen to face his rival, he has revealed that time is running out.
The 29-year-old told Sky Sports News: "All they have to do is pick the phone up and speak to my promoter Eddie Hearn and that fight could get made.
"I'm only really wanting to give him the chance because the fans are desperate for that fight. I think there's going to come to a stage where he's run out of time and I will move on to bigger fish in the division."
Brook will attempt to defend his world title against Frankie Gavin on Saturday night, while Khan meets Chris Algieri in New York on Friday evening.
