Legia Warsaw have said they will not sell tickets for the Champions League fixture at Borussia Dortmund later this month.
UEFA told ESPN FC that "there is a provisional suspension pending a final decision on Nov. 10" after Legia fans clashed with Spanish police prior to the 5-1 defeat at Real Madrid last month.
Twelve people were arrested and seven injured, and in the aftermath the club said they would "ask for a significantly reduced number of tickets" for the Dortmund game and would "check every buyer individually."
But on Monday, they confirmed that they would not sell tickets for the Nov. 22 fixture to their own fans as a "preventative measure."
Legia played last week's 3-3 draw with Real Madrid behind closed doors after trouble marred their first Champions League home fixture against BVB in September.
They had been charged with six offences after a small but organised minority in the 28,000-strong crowd tried to attack the away fans, using pepper spray against security staff.
