Bulgaria may have to play England in a partially closed stadium in October after being charged by UEFA over the alleged racist behaviour of fans.
The European governing body has opened disciplinary proceedings against the Bulgarian Football Union after incidents involving supporters during Monday’s Group A qualifier against Kosovo in Sofia.
Press Association Sport understands the charges relate to chants against ethnic Albanians.
A hearing will take place on July 18 and, if found guilty, Bulgaria would face the minimum punishment of a partial stadium closure for their next home game – the October 14 visit of England.
England currently top the Group A standings with six points from two games. Bulgaria, who lost 3-2 to Kosovo this week, are bottom with two points from four outings.
Last year England had to play a UEFA Nations League match in Croatia in a fully closed stadium after the hosts were punished over the appearance of a swastika on the pitch.
