Celtic winger Aleksandar Tonev has been charged with racially abusing Aberdeen defender Shay Logan.
The 24-year-old Bulgarian, who is on loan from Aston Villa, has been called to a Scottish FA hearing on 9 October.
Tonev must answer a charge of "excessive misconduct by the use of offensive, insulting and abusive language of a racist nature".
The midfielder has until 26 September to respond to the governing body's notice of complaint.
Tonev and Logan were direct opponents for much of Saturday's match, which Celtic won 2-1.
