FREMANTLE has dropped Josh Draper and Quinton Narkle for Thursday night's crucial clash against Collingwood, which has confirmed four changes.

The under-fire Dockers are coming off a poor performance against St Kilda last week and Draper and Narkle have been omitted.

Gun midfielder Hayden Young makes way after his serious hamstring injury, with Patrick Voss back from suspension and Cooper Simpson called up for his first AFL game since round eight last year.

Midfielder Neil Erasmus has also been recalled.

Coming off a five-day break following their loss to Geelong, the Magpies have opted to rest some veterans for the trip to Perth.

Scott Pendlebury, Jordan De Goey and Brayden Maynard will miss, as will Brody Mihocek (abdominal strain).

Jeremy Howe returns alongside Ed Allan, Lachie Sullivan and Oleg Markov.

Young key forward Charlie West is among the emergencies as he waits for his AFL debut following a minor foot issue last week.
