Mohammed Bin Hammam has lost an appeal at the Court of Arbitration for Sport over his current ban from football, FIFA has confirmed.
The Qatari, who had a lifetime ban from the game overturned by CAS in July, was challenging a secondary sanction that prevented him being involved in national or international football matters for an initial period of 90 days.
The ban on Bin Hammam was designed to clear the way for the world governing body's ethics committee to fully investigate allegations of financial mismanagement and corruption pertaining to his time as president of the Asian Football Confederation.
Bin Hammam has claimed allegations against him are politically-motivated after he challenged the incumbent Sepp Blatter for the FIFA presidency last year.
A statement released on FIFA's website this evening read: "The Court of Arbitration for Sport (CAS) has rejected the request for provisional and conservatory measures lodged by Mohammed Bin Hammam against the decision pronounced by the FIFA Appeal Committee on 17 August 2012, which confirmed the previous decision of the Chairman of the Adjudicatory Chamber of the Ethics Committee provisionally banning Mohammed Bin Hammam for a period of 90 days."
