During the match between the Czech Republic and Croatia on 17 June in Saint-Étienne, Croatian hooligans threw flares onto the Stade Geoffroy-Guichard pitch, causing referee Mark Clattenburg to halt the match just before its end, and fans fought among themselves. A steward was struck by a firecracker after a Croatian fan threw it onto the field and striker Ivan Perišić was nearly struck by a flare. A total of eight flares, as well as other objects, were thrown into the field. The team unsuccessfully tried to calm the crowd and Clattenburg moved every player into the center of the field to avoid injury.
