The Celtic winger has regularly been the subject of abuse since moving north in August 2016 without a word being said by the football authorities.
Sinclair has previously left it to others to deal with the type of abuse which has largely been wiped out of English football over the last decade.

Like most problem issues, in Scotland the preferred approach is to look the other way and pretend that it never happened.
Show Racism the Red Card (Scotland) issued a half hearted statement about alleged abuse, there is nothing alleged about the clear and obvious abuse of the player.
Neither Aberdeen, the SPFL or PFA (Scotland) have commented on the matter.
As well as racial abuse inside grounds Sinclair has also been under attack in a lounge at Glasgow Airprort, no further action was taken against those involved.
