BRISBANE Roar have suffered another injury setback, with a knee problem to sideline key defender Luke DeVere for at least 10 weeks.
DeVere was forced off in the first half of the Roar's 3-3 weekend draw with Wellington after being tackled by Phoenix attacker Roy Krishna.
He has been diagnosed with a grade two plus medial ligament strain.
DeVere is the second defender the Roar have lost in the space two matches after left back Corey Brown tore his hamstring in the previous week's 2-1 loss to Newcastle.
Brown is set to return before DeVere, whose bad luck with injuries continues.
"He's disappointed because he's had such a bad stretch of injuries," Roar coach John Aloisi said.
"It's very unfortunate for him."
It's expected DeVere, who tore his calf last season, won't be back until Brisbane's January 5 clash against Western Sydney Wanderers at the earliest.
With another of the Roar's central defenders, Daniel Bowles, not due back from his knee reconstruction also until January, Aloisi hasn't ruled out signing an injury-replacement player as cover for DeVere.
"It's something that we'll be discussing. We're considering our options." the Roar coach said.
Experienced duo Jade North and Avraam Papadopoulos are set to be the last-placed Roar's central defensive pairing against Central Coast Mariners on Sunday at Suncorp Stadium.
But midfield enforcer Thomas Kristensen is set to be sidelined for at least another week with a hamstring problem.
The former Danish international has not played since Brisbane's 5-1 FFA Cup loss to Melbourne Victory on August 9.
