Amir Khan's new trainer will be announced at a press conference on Thursday.
The 21-year-old has parted company with Salford-based Oliver Harrison after winning all his 17 professional fights since turning pro in 2005.
The Commonwealth lightweight champion looks set to team up with a higher-profile trainer in Britain or the United States as he presses for a world title bid.
Khan's promoter Frank Warren will hold a press conference in London on Thursday where it is expected he will announce the Bolton fighter's new coach.
A Sports Network spokesman said: "We're looking to announce the new trainer on Thursday.
"Frank has been speaking to Amir about it. There were a few trainers in the frame - a couple of British trainers and a few Americans."
Several names reportedly in contention for the position are Americans Buddy McGirt, Freddie Roach and Roger Mayweather.
McGirt, a former trainer of the year, already works with former British light-middleweight title challenger Matthew Macklin and Liverpudlian prospect Paul Smith and has previously trained world champions including Arturo Gatti and Antonio Tarver.
Khan spent time in Las Vegas recently with current pound-for-pound king Floyd Mayweather and his trainer/uncle Roger - which he described as "an amazing experience" - while Roach is also regarded as a top trainer having worked with the likes of Oscar De La Hoya, Manny Pacquiao and Bernard Hopkins.
Khan's next fight will be at Birmingham's National Indoor Arena on June 21 against an as yet unspecified opponent.
