Khan moves to clarify Parkinson's disease comments about former trainer Roach

Amir Khan has defended himself in the face of strong criticism for appearing to blame Freddie Roach's Parkinson's disease for his split from the trainer.

Former undisputed light-welterweight champion Khan and Roach parted company in the wake of his upset defeat by Danny Garcia in August and the 25-year-old has since appointed Virgil Hunter as his coach.
