COLLINGWOOD and Port Adelaide will take unchanged line-ups into their crunch clash at the MCG on Saturday.

Port is clinging to eighth spot and desperately needs a win to shore up a finals spot, but will take on the Pies without injured star forward Charlie Dixon.

Power ruckman Paddy Ryder (hip and Achilles tendon) is also under an injury cloud but retained his place in Port's 22 when it submitted its final team 90 minutes before Saturday's 1.45pm opening bounce.

Fifth-placed Collingwood will start the match less than three percentage points behind fourth-placed Hawthorn and needs a win to keep its hopes of a top-four spot alive.

Magpie Nathan Murphy will make his debut against the Power after being named as a late change on Friday when Sam Murray withdrew from Collingwood's team for personal reasons.
