Under-pressure West Coast wingman Lewis Jetta looks to have suffered a pre-Christmas injury setback after limping off Lathlain Park on Monday.

The players were only about 15 minutes into the almost two-hour session in wet conditions when Jetta pulled up and left the field.

The 28-year-old watched from the dugout with his left calf iced while his teammates completed the session.

Star ruckman Nic Naitanui failed to join full training as promised last week.

He trained mostly away from his teammates completing some running and kicking. He joined in match simulation only to palm the ball down from throw ins opposed to part-time ruck coach and retired journeyman Jonathan Giles.

Naitanui denied last week he had had a setback in his return from a knee reconstruction.

Dual Coleman medallist Josh Kennedy was also on light duties, running laps with rising defender Tom Barrass.

Elliot Yeo, who is being eased in due to a hip injury, appeared to be an absentee after signing a new five-year deal on Friday.

Gun midfielders Luke Shuey and Andrew Gaff both moved well, as did veteran forward Mark LeCras.

Liam Ryan and a slimmed down Willie Rioli were both lively during ball movement drills.
