St Kilda have made a late change ahead of their clash with Port Adelaide at the Adelaide Oval on Saturday afternoon.

Rowan Marshall has been withdrawn from the Saints' 22, while Daniel McKenzie has replaced him in the side.

Marshall made his debut against Sydney last weekend at the SCG, and collected 14 disposals and four marks.

McKenzie will come in for his fifth match of the year for St Kilda.

Port Adelaide will go into the match as selected.
