Sydney have confirmed that ruckman Peter Ladhams will miss a "number of weeks" after suffering an ankle injury in Round 10.

Ladhams was stretchered off in the Swans' win over North Melbourne after landing awkwardly on his right ankle, with the club now confirming that the 25-year-old has suffered a lateral ligament injury.

Sydney head physio Damian Raper confirmed the news to club media on Wednesday, revealing that Ladhams would be sidelined for weeks. The ruckman has played nine games so far this season, averaging 15.2 disposals and 20.2 hitouts per game.

"Peter sustained a significant lateral ligament injury to his ankle in the third quarter against North Melbourne," Raper said.

"His recovery is in the early stages, but we expect him to miss a number of weeks."

Tom McCartin remains unavailable for selection has he continues to deal with ongoing concussion symptoms as the club commits to taking a "conservative approach" with the 23-year-old.

"Tom's symptoms continue to improve, however he will not be available for selection this weekend against Carlton," Raper said.

"The club will continue to take a conservative approach and ensure he is asymptomatic before he returns to play."

Callum Mills (calf) and Logan McDonald (ankle) are both continuing their respective recoveries after being sidelined for lengthy stints, while co-captain Dane Rampe is back in full contact training as the club aims for his return post-bye.

"Callum's rehabilitation on his calf injury is going well. He has commenced introductory running drills and strength training," Raper said.

"Logan is expected to miss at least 8 weeks with a medial ankle sprain. He began rehabilitation this week but remains in a boot.

"Dane's neck injury continues to improve. He has increased his strength work and is in full contact training."

Sydney will face Carlton in a Friday night clash in Round 11, scheduled for 7:50pm AEST at the SCG.
