Kell Brook claims Amir Khan fight is 'gone for this year'
Kell Brook has ruled out a 2015 fight with British rival Amir Khan to focus on a potential clash with Floyd Mayweather or Manny Pacquiao.
Representatives of the 28-year-old Sheffield boxer were in talks about a summer date with Khan.
But Brook has now put that to one side with one eye on a possible meeting with the winner of the May 2 Mayweather-Pacquiao welterweight bout.
"I think the Amir Khan fight is gone for this year," said Brook.
Brook defends his IBF welterweight title against Jo Jo Dan in Sheffield on Saturday.
"I'm the world champion and I will fight some other massive name," he added. "I'm not interested in what he [Khan] does next now.
"It makes sense to do a unification fight. No contact has been made yet with either of them [Mayweather or Pacquiao] and I'm just focusing on my mandatory challenge at the moment.
"But I want to be involved in the big fights."
Brook won the IBF world title last August with a points decision over Shawn Porter in the United States.
The Dan fight will be his first since he was stabbed while on holiday in Tenerife last September.
