Harrison (left) and Khan: in happier times
Amir Khan will be trained by Dean Powell for his next fight.
The unbeaten 21-year-old confirmed he has split with Oliver Harrison, the trainer for all of his previous 17 professional contests.
"A breakdown in communications" was the reason for the decision to part company with Harrison, revealed Khan's father Shah.
Powell, who has trained former world champions Duke McKenzie and Lloyd Honeyghan, will work with Khan until his next fight at Birmingham's National Indoor Arena on June 21.
Promoter Frank Warren is hoping to announce the opponent for the Birmingham fight next week.
A decision on a permanent trainer will be taken afterwards, with Khan possibly looking to America.
