Amir Khan's appeal against his defeat by Lamont Peterson has been rejected by the International Boxing Federation, according to reports.
Peterson secured a controversial victory over Khan this month, claiming his IBF and WBA light-welterweight crowns, after the Bolton fighter twice suffered points deductions.
Khan heavily criticised referee Joe Cooper after the fight and his camp decided to appeal.
However, www.skysports.com quoted IBF championships chairman Lindsay Tucker as saying: "We found no discrepancies that would affect the outcome or the result of the fight."
A rematch between the pair is expected to take place next year.
