Celtic goalkeeper Artur Boruc has been called to appear before the SFA disciplinary committee over an alleged gesture made to Rangers fans during last month`s Old Firm derby.
The Pole has been ordered to face the committee on September 16 over a charge of improper conduct.
The SFA review panel decided Boruc had a case to answer after studying photographs of the player which appeared in the press following Celtic`s 4-2 home defeat on August 31.
Boruc suffered a miserable afternoon as he gifted Kenny Miller Rangers` fourth goal when he fumbled a tame cross into the striker`s path.
Boruc was also beaten at his near post for Daniel Cousin`s opening goal on the day stories about his private life made the front page of some newspapers.
The Poland goalkeeper, who was left out of his country`s opening World Cup qualifiers following a breach of discipline, will now face a trip to Hampden to explain his actions.
A statement on the SFA`s website read: ''Press photographs showing the player making a one-fingered gesture were considered by the review panel.
''The player has been called to appear before the disciplinary committee at its next meeting on September 16.
''Before the meeting, the player has to respond with his comments on the alleged misconduct and to the material considered by the review panel.
''If the disciplinary committee finds the player to be guilty of improper conduct, it may impose any penalty on the player.''
Boruc has found himself in trouble over several similar incidents since joining Celtic in 2005.
The former Legia Warsaw player was cautioned by Strathclyde Police for breach of the peace for gestures made to Rangers fans during a match in February 2006.
Police raised concerns after Boruc ran across the Ibrox pitch with a 'Champions' flag following an Old Firm defeat towards the end of the 2006/07 season.
The goalkeeper refused to shake hands with Rangers players following a defeat in October last year and sported a 'God bless the Pope' T-shirt after a 3-2 triumph over Celtic's Glasgow rivals in May.
Boruc has also been accused of gesturing towards Dundee United fans and was involved in two separate incidents at Hibernian last season, the second of which earned him a booking after he waved towards home fans following a Celtic win.
The 28-year-old was suspended from the Poland squad for their qualifiers against Slovenia and San Marino after apparently breaking a curfew with two team-mates following a friendly against Ukraine last month.
Reports then claimed Boruc had been fined £50,000 by Celtic for his off-field behaviour during the club's pre-season trip to Holland.
