UEFA fined the Russian soccer association $150,000 on Wednesday after its fans attacked stadium stewards following a match at Euro 2012.

The incident occurred in Wroclaw, Poland after a 4-1 win over the Czech Republic on Friday as Russian fans were filmed fighting with stadium staff.

Four stewards were treated for injuries at a hospital, although none were considered to be serious.

In addition to the fine, Russia could be deducted six points in its Euro 2016 qualifying group for a repeat offense.

Russia is also being investigated for claims that its fans racially abused Czech Republic defender Theodor Gebre Selassie, who is black, while further "improper conduct" charges could follow for the behavior of Russian fans during a 1-1 draw with Poland on Tuesday.
