Defender Garrick Ibbotson appeared on the training track this morning at Fremantle Oval, but his movement was heavily restricted as he continues to nurse a shoulder injury.
The 26-year-old was a surprise figure as he took part in the session's initial warm-up, with the right shoulder he dislocated against Hawthorn on Friday night heavily strapped.
Ibbotson held his right arm in a rigid position as he initially stretched and completed several short run throughs.
He moved away from the main group after about 15 minutes to concentrate purely on running exercises.
The rebounding backman has been pencilled in to miss up to four weeks with the injury, although surgery on the joint is still yet to be ruled out.
Chris Mayne and Michael Walters did not appear on the track as expected.
The club will wait for up to 10 days to see if heavy swelling on Walters' left ankle goes down, but the forward is likely to need surgery to repair a dislocated tendon in an operation that could rule him out for the season.
Mayne also injured his left ankle against the Hawks. He will need to pass a fitness test to play against Essendon at Patersons Stadium this Sunday, but is considered an unlikely starter.
Hayden Ballantyne and David Mundy were amongst a group of key Dockers who ran laps during the training session rather than taking part in skills work.
