West Coast premiership coach John Worsfold will be an observer in the Crows coaching box on Saturday at the request of coach Phil Walsh.

Worsfold, who was the senior coach at the Eagles when Walsh spent five seasons as an assistant with the Club, will review the workings of the box in Adelaide’s NAB Challenge clash with Port Adelaide at AAMI Stadium.

A 200-game player with West Coast, Worsfold coached the Club from 2002-2013, including the 2006 premiership.
