Port Adelaide have made a late change ahead of their clash with Geelong at the Adelaide Oval on Saturday night.

Forward Todd Marshall will miss the match for the Power, and has been replaced by former North Melbourne forward Lindsay Thomas.

Thomas made the move from North Melbourne to the Power at the end of last season as a delisted free agent.

The Cats will go into the clash as named.
