Amir Khan’s trainer says the Bolton fighter needs to commit more to training if he is to continue fighting at the top level.

The 32-year-old’s future is in the balance after his bizarre defeat to WBO World welterweight champion Terence Crawford in April.

Khan was pulled out of the fight by cornerman Virgil Hunter after being hit by a low blow in the sixth round when way behind on the judges’ cards at Madison Square Garden in New York.

Many have called for the Olympic silver medallist to retire but he has already said he intends to fight on.

The Bolton News:

"I would like to see him commit to many training camps in between fights and to work on his weaknesses before he makes that final decision to really see if his skills are gone, or if he is just letting them lay in a pile and deteriorate slowly,” Hunter told BBC Sport.  

"He never has practice in between fights. He trains hard for 10 weeks but it's not enough.

"There's little things that he does that cause him to be out of sync.

"His timing is off. His distance is not where it should be. He doesn't have a sense of range and distance and those things are not due to age. That's from practice.

"His hand speed is still there but his sense of distance and range is not there and that's what he needs to work on."

There remain options out there for Khan, most likely finally settling his differences with domestic rival Kell Brook although the Sheffield man could be the next to challenge pound-for-pound star Crawford.

A former unified world super-lightweight champion, Khan has 33 wins and five defeats on a professional record that has seen him take on the very best.
