Aberdeen's Vicente Besuijen has been told he should've received a red card during his side's defeat to Rangers on Saturday.
The Dutchman was booked by referee John Beaton for a lunge on Scott Arfield but two former grade 1 officials reckon he got off lightly.
Steve Conroy and Des Roache suspect Besuijen was seeking "retribution" on the Rangers midfielder after he too escaped punishment for a foul on Lewis Ferguson that left the Dons star in agony.
