Sydney confirmed on Saturday that Gulden will have surgery on Sunday morning, with a return date yet to be determined.

Gulden became the latest star injured during what has been a tough pre-season.

Western Bulldogs captain Marcus Bontempelli, Port Adelaide star Zak Butters, Greater Western Sydney midfielder Tom Green, Fremantle gun Hayden Young and Sydney skipper Callum Mills have been ruled out to begin the season.

Carlton spearhead Charlie Curnow, St Kilda forward Max King and Collingwood midfielder Jordan De Goey are under injury clouds for their clubs' respective openers.
