WBA light-welterweight champion Amir Khan has announced a deal with United States-based Golden Boy Promotions.
Khan, who has been promoted by Frank Warren since turning professional in 2005, has won 22 of his 23 pro fights and became a world champion last year.
But the Bolton 23-year-old is to link up with Oscar De Hoya's promotional company as he looks to crack America.
"I'm ready to fight anyone, anywhere, anytime and know Golden Boy will help me accomplish these goals," said Khan.
"I am really happy Khan Promotions is partnering with Golden Boy.
"I know that together they will be the right team to help me continue my career as an elite fighter and to expand my fan base to the United States and around the world."
