Melbourne City FC can confirm that Damien Duff will be sidelined after the winger sustained a calf injury in Sunday’s 1-0 win over Brisbane Roar in the Hyundai A-League.

Duff was replaced at half-time in the Round 9 match and scans on Tuesday revealed the former Ireland international had suffered a tear, which will rule him out of action until the New Year.

Duff has started all nine matches Melbourne City FC has played this season, registering 766 minutes for the Club.
