Melbourne Victory star James Troisi will miss up to a month after undergoing surgery on a fractured collarbone.
Troisi, 28, suffered the injury during the Victory's 1-1 draw against the Brisbane Roar in the A-League season opener on Friday.
Scans revealed a fracture and Troisi underwent surgery on Saturday, the club confirmed.
The injury is a blow to Victory, who looked set for three points before Luke DeVere's dramatic late equaliser at Suncorp Stadium.
Kevin Muscat's men take on rivals Melbourne City on Saturday and are likely to regain attacker Marco Rojas from international duty.
