UEFA has launched an investigation into the conduct of Russia's fans during their Euro 2012 opener against the Czech Republic.

It has been reported that four stewards were hospitalised following Russia's 4-1 win in Wroclaw.

Czech right-back Theodor Gebre Selassie was also reported to have been racially abused by sections of the Russian support.

UEFA have now released a statement, which reads: "UEFA has opened disciplinary proceedings against the Football Union of Russia for the improper conduct of its supporters at Friday's UEFA EURO 2012 match against the Czech Republic.

"After having looked at the security reports and available images, UEFA has today announced that disciplinary proceedings have been opened against the Football Union of Russia (RFS) for the improper conduct of its supporters (crowd disturbances), the setting-off and throwing of fireworks and the display of illicit banners. The control and disciplinary body will review the case on Wednesday, June 13.

"In addition, regarding reports of alleged abuse directed at Czech Republic players from Russia fans, UEFA is investigating this further and is working with FARE (Football Against Racism in Europe) to collect more evidence."

It is unclear what course of action UEFA could take against Russia should their supporters be found guilty of any wrongdoing.
