BoxingScene.com was advised by Shah Khan, father of WBA 140-pound champion Amir Khan, that strength and conditioning coach Alex Ariza will no longer be working with his son. There are several rumors floating around as the exact reason for Khan's replacement of Ariza, but Shah would not comment on any of the stories being circulated. He told BoxingScene that both parties needed to move on.

Khan is trained by Freddie Roach, who is close friends with Ariza. Shah made it clear that Ariza being dropped from the team will in no way affect his son's relationship with Roach. A new strength and conditioning coach is being brought in. 

"We just needed to move on. Amir needed to move on. Freddie is going to bring in another conditioning coach. He already mentioned a name, but we'll wait [to disclose the name] until he gets everything." Shah told BoxingScene.com.

Khan returns on April 16 at MEN Arena in Manchester. No opponent has been set.
