Rangers could face further UEFA disciplinary action after Czech police revealed that the match delegate from their defeat in Jablonec reported their fans for spilling onto the pitch.
The Ibrox club were knocked out of the Europa Conference League after a penalty shootout in a disastrous defeat. They were then ordered to play their next home Scottish Cup match behind closed doors, along with Celtic, after last season's Old Firm quarter-final was marred by fan clashes.
Match delegate report
Now they will have to wait and see if they are to face further punishment after their visit to the Czech Republic, after their fans' actions were reported by the match delegate, according to local police.
Municipal police spokeswoman Dagmar Sochorova said: "A total of 5,563 spectators watched the match, of which 650 were Rangers fans."
"We received information from the delegate about possible unauthorised entry of Rangers fans onto the playing pitch and into the home section."
Flag row and previous sanctions
"Jablonec fans stole one Rangers flag and destroyed three of their flags, which we treated as a violation."
Rangers have already been punished by UEFA this season because of a delay to the kick off in Poland for their defeat to Jagiellonia Bialystok. They were fined £13,000.
