Celtic winger Aleksandar Tonev was hit with a Scottish Football Association charge over alleged racial abuse on Friday.

Tonev, on loan from Aston Villa, has been accused by Aberdeen full-back Shay Logan of making a racial slur during his team's 2-1 defeat at Celtic last weekend.

The Scottish Football Association compliance officer issued a notice of complaint accusing Bulgaria international Tonev of "excessive misconduct by the use of offensive, insulting and abusive language of a racist nature".

Tonev, who was making his debut for the Scottish champions in the Aberdeen fixture, has denied the allegations and has until September 26 to respond, with a Hampden Park hearing scheduled for October 9.

Hoops manager Ronny Deila admitted he was surprised Tonev had been charged and claimed he had forgotten about the row.

"The journalists asked me earlier today and I couldn't remember what they were talking about," he said.

"I can't understand the problem, they are coming with something against us, that the player said didn't happen and I really believe him. That's it, finished."
