The West Coast Eagles and senior coach Adam Simpson have mutually agreed that his 11-year tenure at the club will come to an end.

Simpson, one of only six senior coaches in the 37-year history of the club and one of only three to lead the club to premiership glory, achieved the ultimate success in 2018 to join Michael Malthouse (1992, 1994) and John Worsfold (2006) in bringing the cup to WA.
