The winger will be on the sidelines until next two months due to an aggravated knee injury
The 23-year-old has been battling with chronic knee damage and aggravated his condition recently hence the need to rectify it with an imminent surgery.
“Kofi Danning won’t be available until December at the earliest because of his own knee reconstruction,” Roar managing director Sean Dobson told the Herald Sun.
“That leaves the Roar with just 16 members of their A-League squad available for Sunday’s clash against Melbourne Heart at Suncorp Stadium.”
Dobson added: “Star Irish recruit Liam Miller faces up to four weeks on the sidelines after tearing his calf, while prolific Albanian striker Besart Berisha will miss at least another week with a hamstring problem. Midfielder George Lambadaridis is out for the season after knee surgery.”
Danning, a transfer target of former Manchester United coach Sir Alex Ferguson, played for Belgian side CS Vise last season. He has featured for the Australian Under-17 and 20 teams but is still eligible to play for Ghana.
