Aleksandar Tonev, the Celtic winger, has been issued with a notice of complaint by the Scottish Football Association over allegations of racist abuse.

Aberdeen full-back Shay Logan accused the on-loan Aston Villa player of a racial slur during his team's 2-1 defeat at Celtic Park last weekend. Vincent Lunny, the Scottish Football Association compliance officer, has issued a notice of complaint accusing Tonev of "excessive misconduct by the use of offensive, insulting and abusive language of a racist nature".

Tonev, who made his Celtic debut against Aberdeen, has denied the allegations and has until September 26 to respond, with a Hampden hearing scheduled for October 9.
