UEFA said it regretted the unrest on the streets of Lille overnight on the eve of the Euro 2016 match between England and Wales, but it stopped short of taking any action to punish fan violence.
French riot police charged and used tear gas to disperse rowdy England fans on Wednesday night.
Police said about 50 people were hurt, 16 of whom were hospitalised.
"UEFA regrets the skirmishes which occurred in Lille last night. Police forces made several arrests and were quick to restore order and keep the situation under control," UEFA said in a statement.
European football’s governing body made no reference to any action it might take.
After violence in Marseille before and after England's 1-1 draw with Russia on Saturday, UEFA warned England that a repetition of fans' violent behaviour could see the team expelled.
UEFA also told Russia that it would be disqualified if there was repeat of their fans' violent behaviour, which included attacks on England supporters in the stadium as the match ended.
Lille was seen as a potential flashpoint for trouble, with Russia also playing in the northern town on Wednesday. The Russians lost 2-1 to Slovakia.
England's match with Wales in the same group takes place in nearby Lens this afternoon.
Separately, police in Lyon said two fans suffered stab wounds in a fan zone there.
Lyon police said one of those wounded, a Frenchman, had told them one of his attackers wore an Albania football shirt. France beat Albania 2-0 in another of Wednesday's games.
Marseille police also said a further 20 Russian fans were to be expelled from France, while three others were to go on trial.
