In another blow to Queensland Roar's waning finals hopes, skipper Chad Gibson has been ruled out of a must-win A-League clash at Perth on Saturday night with a knee injury.
The defender will undergo scans on Wednesday to learn the full extent of the injury sustained in Queensland's heartbreaking 4-2 loss to leader Adelaide United last Sunday night.
Midfielder Massimo Murdocca is in doubt with an ankle injury suffered in a tackle by Adelaide's Carl Veart - one of several first half incidents Queensland is still fuming about.
Queensland was frustrated that Veart was not punished for a first half "swipe" that brought down Murdocca and led to a 30th minute goal by Chinese striker Qu Shengqing that turned the game on its head.
Adelaide had equalised a minute earlier when Roar goalkeeper Tom Willis was controversially penalised for bringing down Qu and Veart converted from the spot.
Roar also claimed its new Brazilian striker Reinaldo was hit in the mouth by an Adelaide player in back-play at the 30 minute mark of his A-League debut.
Queensland spokesman Neil Favager said Reinaldo was forced to consult a dentist when the team returned to Brisbane on Monday.
"He had a loose tooth and a split lip but he's fine," Favager said.
"In terms of his performance, Reinaldo give us a different dimension up front, something we didn't have.
"Of the positives to come out of the game, he was one of the greatest ones."
Favager ruled out making a complaint to the league over the controversial incidents.
"We see no need to do that, the game is gone," he said.
"It's 4-2 to Adelaide and we've just got to focus on our next five matches.
The Roar will decide whether Murdocca will fly out with the team on Friday after being reassessed at training.
Second-last Queensland must win its remaining five games to seal a top four finals finish, starting against fifth-placed Perth this weekend.
The main concern is skipper Gibson who left the field at halftime against Adelaide.
Roar fitness co-ordinator Tony Ganter said it was the same knee that kept Gibson out of the last two games but it was an unrelated injury.
"The old injury was ligament damage, but this one looks like it could be a cartilage tear," Ganter said.
Remo Buess is expected to take the captaincy reins for Gibson.
"The hardest thing for me right now is the thought that I might not be able to be out there with the team in our most crucial phase of the season," Gibson said.
"We need results badly now and I desperately wanted to play my part in helping to get them.
"I'm keeping my fingers crossed that the scan won't reveal anything serious."
