LIVINGSTON face the possibility of being thrown out of the Irn-Bru Cup after being charged with fielding an ineligible player in their 2-1 away victory over Crusaders in Belfast.
Defender Alan Lithgow played the full 90 minutes in Livi's win which set-up a home quarter-final tie against The New Saints.
But it has been reported to the SPFL that the 28-year-old played while under a Scottish FA suspension, having been sent off at East Fife on 24 September.
Livingston have been requested to attend an SPFL hearing on October 24 when their punishment could range from being given a warning to being ejected from the last eight.
Spartans and East Stirling have both been kicked out of the Scottish Cup in recent years for fielding ineligible players and the same offence by Dundee United in a Premiership game at Inverness last season saw the Tayside club docked three points and fined £30,000.
The West Lothian club are due to face TNS on Sunday 13 November, live on S4C and BBC Alba.
