Virgil Hunter has scoffed at suggestions that Amir Khan is not a durable fighter.

Khan lost back-to-back fights against Lamont Peterson and Danny Garcia last year to give credence to the theory that he cannot withstand an onslaught from his opponents.

However, Hunter, who has been training Khan since late last year, has dismissed the talk that his fighter is weak and thinks it is a "misconception" of the 26-year-old.

"I think we have to acknowledge that toughness and durability [he has], so I don't think that misconception [of being weak] should be tossed around lightly," Hunter is quoted as saying in The Telegraph.

"Amir's a tough, tough kid. I don't want that misconception of Amir Khan. It's a misconception that because he's a former Olympic medallist, he is over-promoted.

"He has had the toughest road to go down, especially because he's successful. To get to the point where he is you have to be strong, you have to be durable, and focused. Nobody gave him that [Olympic] silver medal."

Khan will fight Julio Diaz in Sheffield next month.
