RANGERS have highlighted various refereeing concerns to the Scottish FA after their 1-1 draw with Aberdeen this week, according to a report. 

It has been reported that the Scottish champions have outlined eight incidents to Hampden chiefs regarding Kevin Clancy's decisions. 

Sky Sports News say that the Premiership leaders have submitted a letter about their concerns. 

And their report states that the club and SFA have held constructive talks about the issues raised. 

It's said that Clancy's decision to send off Ryan Kent for a foul on Scott Brown was one of the highlighted incidents. 

Another incident included in the letter was the collision between Jonny Hayes and Borna Barisic late in the match, which left the Croatian left-back with a bloody nose.

The Ibrox side are also said to be keen for an explanation as to why Lewis Ferguson's penalty was no retaken. 

Replays showed that the ball moved due to the wind at Pittodrie, with FIFA rules stating that spot-kicks must be retaken if the ball is in motion.

Aberdeen manager Stephen Glass was also critical of the referee after the match with his side denied a penalty when Allan McGregor made contact with Ryan Hedges inside the area.
