Celtic will discover if their Europa League reinstatement stands on Tuesday - two days before their scheduled opener against Atletico Madrid - after Sion submitted an appeal against their expulsion late on Thursday night.
UEFA confirmed an appeal hearing would be heard on September 13, the day before Celtic had planned to fly to Spain.
Sion had revealed on Monday they planned to appeal and UEFA were expected to convene a panel on Friday, but the delay throws up even more uncertainty for the affected clubs and Celtic fans hoping to travel to Spain.
