Gold Coast United's van den Brink cleared of serious injury
The Dutchman, who scored a cracking goal on the stroke of half-time in the defeat, fell uneasily on his head after an aerial challenge with Sergio van Dijk and was taken for precautionary X-rays after the match.
But results have shown no damage but van den Brink is likely to miss the clash with North Queensland Fury on Wednesday night.
"We're missing Dino and James (Brown) with suspension and Bas might be doubtful but we have to use the full depth of the squad and the boys have got to be ready and prepared," Rees told the Gold Coast Bulletin. "It's disappointing but we have to look forward now to our game next Wednesday and close that gap on (second-placed) Adelaide."
