Uefa has charged the Spanish and Russian football associations for racist chanting by fans at Euro 2012.
A Uefa statement said the Spain case relates to the Italy game on 10 June while Russia's 8 June match against Czech Republic is also under investigation.
A Uefa disciplinary panel will deal with the cases on Thursday.
Spain and Russia are likely to receive financial penalties if the cases are proven.
Russia have been punished three times already by Uefa for the improper behaviour of their fans during the tournament.
