Martin O'Neill's bid to overturn a one-match ban from Celtic's game against Porto tomorrow night has been thrown out by the Court of Arbitration.
The Parkhead boss was originally suspended by UEFA after he was ordered to leave the dugout by referee Hellmut Krug near the end of Celtic's 3-2 Champions League defeat against Juventus in Turin last Tuesday.
O'Neill had argued with Krug after he awarded Juventus a controversial late penalty.
In a statement issued today the court said: "The president of the CAS Appeals Arbitration division decided to dismiss the request for interim measures noting that the jurisdiction of CAS was not established in the present case.
"Consequently, the decision made by the UEFA Control and disciplinary body remains in force."
The decision means O'Neill is banned from the dressing room, tunnel and touchline for the Celtic Park tie. -PA
