Brisbane have suspended Frank Farina after the Roar boss was charged with drink driving on Saturday morning.
The former Australia coach was relieved immediately of first-team duties, leaving assistant coach Rado Vidosic in charge for the 1-0 home defeat by Gold Coast on Sunday.
Roar chairman Chris Bombolas underlined the club will investigate the matter thoroughly before making any decisions over Farina's future.
"We'd like to talk personally with Frank in front of the whole board to discuss the matter and discuss the direction of the club," Bombolas said.
"We say to the fans 'stick by us'. We want the focus and the attention turned back to what's happening on the pitch, rather than matters that have happened off the pitch."
Meanwhile, Gold Coast United climbed to second in the A-League as Joel Porter's 31st-minute goal was enough to seal a 1-0 victory against Brisbane Roar at Suncorp Stadium.
Porter was on hand to take advantage of Roar defender Bob Malcolm's miscued header and tap home at the far post.
Malcolm himself had headed over from close range with quarter of an hour gone and Sergio Van Dijk did the same with the goal at his mercy after 41 minutes. Van Dijk also saw an equaliser ruled out just before the break when Mitch Nichols was adjudged to have fouled Gold Coast keeper Jess Van Strattan in the build-up.
Elsewhere, Daniel McBreen's goal 14 minutes from the end salvaged a 1-1 draw for North Queensland Fury at Central Coast Mariners.
Matt Simon gave the hosts the lead with the quickest goal in A-League history when the striker took advantage of Chris Tadrosse's poor backpass and fired past goalkeeper Paul Henderson with just 14 seconds gone at Bluetongue Stadium.
The Mariners also had a goal disallowed for offside five minutes after the break before McBreen headed home the equaliser in the 76th minute to ensure the points were shared.
