Legia Warsaw have been told by UEFA to play their next Champions League home game against Real Madrid behind closed doors following racist behaviour and other crowd disturbances against Borussia Dortmund.
The European football body has also fined the Polish club 80,000 euros (89,600 dollars).
During Legia's 6-0 defeat on September 14, Legia "ultra" fans attempted to storm the Dortmund fan section. UEFA cited racist behaviour and crowd disturbances and said fans set off fireworks and threw missiles, stairways were blocked and there was insufficient organization.
Legia also lost 2-0 at Sporting Lisbon on Tuesday and are now last in Group F before the visit of Real on October 18.
