Europe's football governing body, Union of European Football Association, UEFA, have threatened to disqualify both England and Russia from the on-going Euro 2016 if their supporters are involved in further violence.
According to Skysports.com, UEFA had already opened disciplinary proceedings against Russia over the behaviour of their supporters at the Stade Velodrome in Marseille on Saturday night.
The game ended 1-1 with Vasili Beretzuzky equalising for Russia in added time after Eric Dier had given England the lead.
There were ugly scenes in the city before and after Saturday's match involving English and Russian fans.
A UEFA statement said: "The UEFA Executive Committee would like to express its disgust for the violent clashes which occurred in the city of Marseille.
"Such unacceptable behaviour by so-called supporters of the national teams of England and Russia has no place in football, a sport we must protect and defend.
"The UEFA Executive Committee has warned both football associations that – irrespective of any decisions taken by the independent disciplinary bodies relating to incidents inside the stadium – it will not hesitate to impose additional sanctions on the Football Association (FA) and the Russian Football Union (RFU), including the potential disqualification of their respective teams from the tournament, should such violence occur again.
"We urge both the FA and the RFU to appeal to their supporters to behave in a responsible and respectful manner.
"We would also like to publicly voice our support for the work of the French authorities and security forces for their efforts to deliver a safe and secure tournament in challenging circumstances."
