UEFA will study the match reports on Monday before deciding whether to take action against the Bulgarian Football Federation over the racist abuse at Friday night's Euro 2012 qualifier with England. The Football Association have already made their feelings known to their Bulgarian counterparts, in addition to the UEFA match delegate.
"UEFA are aware of the situation," said a spokesman.
"We will study the reports, including the delegate's report, on Monday."
The issue of racism has been a persistent problem during England's recent ventures into eastern Europe.
