Scans have revealed that defender Aliir Aliir sustained a minor medial ligament strain in the win over Geelong.
The 22-year-old landed awkwardly after a marking contest in the opening quarter and took no further part in the match.
Swans Head of Football Tom Harley says Aliir had scans on Saturday.
“The scans have revealed Aliir has suffered a low-grade medial strain," Harley said.
"We will continue to monitor Aliir and assess him as the week progresses. He remains a chance to play.”
Midfielders Luke Parker and Josh Kennedy also had precautionary scans after suffering knocks to the knee and both have been cleared.
Meanwhile co-captain Jarrad McVeigh (calf) and Rising Star Callum Mills (hamstring) will be tested at training this week.
