Perth Glory missed a golden chance to claim three points against a 10-man Brisbane Roar after Besart Berisha was sent off in Friday night's 0-0 draw at nib Stadium.
Berisha was given his marching orders in the 30th minute after receiving his second yellow card of the evening for a crude challenge on Glory defender Michael Thwaite.
The Albanian international was lucky not to have been sent off after just 20 seconds when he jumped into Thwaite's ribs during an aerial contest.
Berisha was fouled by Steven McGarry five minutes later and collapsed to the turf in agony, however he was soon back on his feet and looking dangerous around goal.
But his night ended on the half-hour mark when he raised a knee into Thwaite and was shown red, much to the delight of the parochial Perth crowd.
Berisha's exit sparked heated scenes on the pitch, with Glory goalkeeper Danny Vukovic and Roar midfielder Liam Miller booked for their involvements in the scuffle.
Despite having an extra man, Glory did not take advantage.
Brisbane midfielder Luke Brattan almost put the visitors in front with a long-range free kick on the cusp on half-time, while Henrique came agonisingly close to finding the top left corner shortly after the resumption.
