Port Adelaide pair Miles Bergman and Jack Lukosius have been ruled out of this weekend's pre-season clash against West Coast. 

Lukosius left the track on Thursday with groin tightness, with the decision made to leave him out of the side to allow him to prepare for the season proper.

Following an incident during Friday's match sim, Bergman has been experiencing irritation around the sensory nerve in his ankle and foot.

The midfielder is expected to be back in full training late next week and will be available for Round 1.
