Sydney will hold livewire Tom Papley back for another week as he recovers from calf soreness.
Papley stepped up his work on Monday, but remained mostly away from the main group.
The Swans will resist the temptation of playing him in Friday's full-scale match simulation.
It will be a huge session before the club goes on a short break prior to ramping up preparations for the season opener against Carlton at the SCG.
The Swans have circled February 19 as Papley's return date, when he will be eased in for a full-scale practice match against the Western Bulldogs.
Although Papley will look on this Friday, the Swans have confirmed Brodie Grundy and Joel Amartey will return from concussion protocols in time for match simulation.
The Swans looked sharp on Monday morning in a wind-affected session and have few injury concerns despite a rash of soft-tissue problems across the AFL.
Taylor Adams returned to the track in a solid running session off the side of the main group.
Adams was knocked unconscious and taken to hospital in a late night incident nine days ago, but is in good spirits and recovering well.
A noticeably stronger Tom McCartin taking on marquee recruit Charlie Curnow was the highlight of the session.
