Uefa has launched disciplinary proceedings against the Football Association over the "inappropriate conduct" of England fans at the Euro 2012 Championships.
The governing body of football in Europe is investigating an attempted pitch invasion by supporters during Friday's game against Sweden.
England won the group D match at the Olympic Stadium in Kiev, the capital city of Ukraine.
Uefa said on its website that it was looking into the "inappropriate behaviour" of supporters and an "attempted invasion of the field of play".
The case will be dealt with by Uefa's Control and Disciplinary Body on June 20.
Sky News sports presenter Chris Skudder said: "It happened after fans celebrated Theo Walcott's equalising goal in the 3-2 win against Sweden.
"Uefa say that was inappropriate.... but the FA are not very happy.
"They may launch an appeal against that, for what they consider was just over-exuberance by the fans."
The Football Association said it was considering its response to Uefa's statement.
A spokesman for the FA said: "We acknowledge Uefa's statement of today, and we will respond accordingly."
A goal each from Andy Carroll, Theo Walcott and Danny Welbeck secured the win for Roy Hodgson's side against Sweden.
It means just a draw is needed from Tuesday's final group match against co-hosts Ukraine for England to secure a place in the knock-out stages of the competition.
For Sweden, the result left them bottom of the standings with no points and ended their hopes of going through.
