Top referee Dermot Gallagher believes Rangers were denied a stonewaller against Dundee United and reckons the hosts should have finished the game with 10 men.
The Ibrox side were left frustrated after the 1-1 Scottish Premiership draw and were miffed by Bobby Madden's decision to wave play on when the Zambian was hauled down by Ross Graham.
Rangers also had a penalty shout turned away by Madden for a handball by Graham before the incident involving Sakala.
