Richmond and Collingwood have named unchanged teams for Friday night’s AFL preliminary final while Melbourne have dropped unlucky youngster Bayley Fritsch.

The Tigers and Magpies are backing their incumbents to get the job done at the MCG.

Reigning Brownlow medallist Dustin Martin’s corked thigh has been a talking point throughout this week but the superstar trained on Thursday and is expected be part of the grand-final qualifier.

West Coast and the Demons have each made one change.

Will Schofield is the recalled Eagle to benefit from the misfortune of teammate Brad Sheppard, who suffered a serious hamstring injury in week one of the finals.

The Demons, wary of West Coast’s star-studded forward line, have recalled Joel Smith for their preliminary final at the expense of Fritsch.

The 21-year-old Fritsch made his debut in round one and has played a total of 23 games this season.
