Amir Khan believes he has a chance of having his defeat by Lamont Peterson overturned on appeal.
The 25-year-old lost his WBA and IBF light-welterweight titles on Saturday night as Peterson won a narrow points decision in Washington D.C.
Khan crucially had two points deducted by referee Joseph Cooper for pushing and insists the decision was unfair.
He said: "We have appealed. In the next seven to 10 days we should find out and it could be overturned."
Khan had Peterson on the canvas twice in the opening round - although only one was counted - and his two-point penalty proved costly after judges scored the fight at 113-112, 113-112, 111-114 in favour of the local fighter.
The Bolton-born fighter is adamant that he won the fight and will fight Peterson again next year regardless of the outcome of the appeal.
Although it is rare to have decisions overturned, WBC light-heavyweight champion Bernard Hopkins has been successful in having October's fight against Chad Dawson changed from a loss to a technical draw.
Khan said: "I was treated unfairly during the fight. Lamont Peterson's coach even said to me that he knows how it feels to be robbed.
"The referee was from Washington so he was always going to favour the home fighter. He walks the streets of DC so if he was fair and took points off Peterson he'd be hated in Washington.
"My titles were snatched off me unfairly. I don't think he'll be refereeing a big fight again.
"I want a rematch in a neutral place with a neutral referee and neutral judges. Not Washington or the UK, somewhere like Las Vegas would be fine."
