Port Adelaide has swung the axe after a disappointing month, dropping four players for tomorrow night's clash with Collingwood.

Coach Ken Hinkley has dumped Tom Jonas, Nathan Krakouer, Andrew Moore and Sam Colquhoun.

Alipate Carlile is also out due to a back complaint.

Cam O'Shea, Tom Clurey, Jake Neade, Karl Amon and Jackson Trengove come into the side for the Power.

The Magpies on the other hand named an unchanged line up.
