Rangers will discover on Monday whether their call to UEFA to investigate the worrying crowd scenes which occurred during their European clash at Osasuna will take place.
Gers chief executive Martin Bain has appealed to Europe's governing body to look into the policing and organisation at the Spanish club's stadium after complaining about a lack of segregation and heavy-handed treatment of travelling fans during Wednesday's 1-0 UEFA Cup defeat.
Rangers captain Barry Ferguson has already branded the treatment of Rangers fans as "out of order".
He told the Scottish Sun: "The organisation was a disgrace and I just don't see our support as one that carries a reputation for trouble.
"UEFA have to look at that because no-one should go through that just to follow their team."
UEFA have confirmed they will wait to receive a report from their security officer present at the last 16 clash before taking any action.
