Sydney has recently lost re-signed key defender Will Edwards to a dislocated ankle.
Edwards debuted this year, and has been a revelation for the Swans in the backline, but is set to miss the remainder of the season.
"To see a player battle like he has for so long to get a chance at AFL with some of the injuries he's already had, to dislocate his ankle and required to go to hospital and get surgery – is devastating for him and the football club and his family,” Sydney coach Dean Cox said.
"To forge out to be a really strong key defender for a young man is great. It'll just be another hurdle that he has to jump, and we'll support him all the way through it."
Cox suggested key defenders Lewis Melican and Joel Hamling would be in line to replace Edwards.
The Swans also have concern with selfless midfielder James Rowbottom.
Rowbottom broke his hand in the first quarter of the victory.
"Knowing James, he'll want to play next week," he joked. "We'll seek medical advice on everything… he'll get his hand looked after and get back as quick as he can."
The Swans remain in second position, with games against Port Adelaide, Essendon and North Melbourne to come.
