England appear to have escaped further punishment from Uefa following further clashes between fans and police in Lille last night.
European football's governing body had threatened to expel Roy Hodgson's team from Euro 2016 if there was a repeat of the fan violence that marred the build-up to their opening match against Russia.
There were reports of 36 arrests and 16 fans having been hospitalised in Lille on Wednesday as French police deployed tear gas to disperse supporters ahead of England's crunch Group B clash with Wales in nearby Lens this afternoon.
Uefa has acknowledged the trouble but argued the situation was kept under control by police. They do not yet appear to have regarded it as sufficient to throw England out of the tournament.
"Uefa regrets the skirmishes which occurred in Lille last night," it said in a statement.
"Police forces made several arrests and were quick to restore order and keep the situation under control."
Both Hodgson and England captain Wayne Rooney have appealed to fans to stay out of trouble.
"As England manager, I am obviously very concerned about the threat which is now hanging over us and the sanctions that could be imposed upon the England team," said Hodgson.
"We worked very hard to get here and we really desperately want to stay in the competition. We appreciate your support at the matches of course, but I am appealing to you to stay out of trouble and to try and make certain that these threats that are being issued are never carried out and we will be able to attempt to do the best we can to stay in this competition by football means."
Russia were given a suspended disqualification from Euro 2016 after their fans stormed England supporters at the end of the 1-1 draw in Marseille's Stade Velodrome on Saturday.
