A promoter of last December's fight had claimed that Mustafa Ameen, the man accused of interfering with the judges' scorecards, was employed by the IBF.
However, the boxing federation have now refuted those claims and in a statement insists he isn't paid for his work on an IBF scheme to help retired boxers.
"Mr Ameen does outreach work for the IBF's Sarb [Special Assistance for Retired Boxers] Education Fund," the organisation said.
"Mr Ameen is not an employee or an official of the organisation, nor does he receive any monetary compensation from the organisation for his efforts."
The IBF went on to say that Ameen was at ringside that night in order to connect with the fighters who the federation provide financial assistance to and not to speak with the judges.
Khan's camp are pushing for the fight to be declared a no contest and for a rematch to be organised, with an appeal hearing set to take place on January 18 in New Jersey.
