Michael Stewart pointed the spotlight on Rangers' "incredible" run of no league penalties conceded after Connor Goldson appeared to get away with one against Aberdeen.
Dons boss Barry Robson was left raging at a "definite" foul in the box on Duk that went unpunished as Rangers eventually picked up a narrow 1-0 win through Todd Cantwell's volley.
January 2022 was the last time the Ibrox side conceded a penalty in the Premiership - ironically against Aberdeen, when Lewis Ferguson earned the Dons a point from the spot - and it's a run which now spans 52 league games.
The defeat also ended Aberdeen's impressive run of seven wins in a row which encompassed five consecutive clean sheets, although Hearts also losing to Celtic means it was no ground lost for Robson's men.
