West Coast have parted ways with 2018 premiership coach Adam Simpson with seven games remaining in the current season.
The club has confirmed its decision to relieve Simpson of his duties midway through his 11th campaign with the Eagles, ending long-serving reign for the North Melbourne great.
"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," a short club statement read.
The club has revealed Simpson has been offered to coach the club's Round 18 game on Sunday against Brisbane, with the departing Eagles coach yet to decide whether to extend his tenure for one more match.
A 243rd game in charge would see Simpson equal Mick Malthouse in second for the most games coached for West Coast.
The Eagles have named assistant Jarrad Schofield as the club's interim coach for the remainder of the season, with his duties to commence this weekend should Simspon decline the option for a farewell game.
Simpson joined the club ahead of the 2014 season in succeeding departed coach John Worsfold, with the club looking to bounce back from a nine-win campaign.

West Coast reached a grand final in their second year under Simpson, losing the season to Hawthorn - the club Simpson worked with as an assistant for four years prior to joining the Eagles.
Simpson led the club to its fourth AFL premiership in 2018 with a five-point win over West Coast.
The past three seasons haven't been as kind to the 48-year-old, who has amassed eight wins from 60 games as the club works through a transition period.
The Eagles haven't won a game since mid-May, having lost their past six - a run that includes a 99-point loss to Adelaide, a 61-point defeat to Hawthorn and, most recently, a nine-goal loss to Melbourne.
