Raiders fans booed ref for no call on a dangerous play, coach Stuart upset on sideline.
Raiders fans booed referee Wyatt Raymond, and coach Ricky Stuart looked filthy on the sideline after the Broncos were not penalised for an elbow to the throat.
Brisbane backrower Jordan Riki carted the ball up in the nation's capital on Saturday night when he lifted his left arm to shield himself.
His forearm and elbow made contact with the throat of Canberra star Hudson Young, who reeled away from the contest and fell to his knees.
