Fremantle coach Ross Lyon has sensationally been sacked as coach of the Dockers.

According to Fox Footy, Lyon was told he would be sacked on Tuesday, with club CEO Steve Rosich also set to be moved out of the club.

Both Lyon and Rosich were contracted for 2020.

“As a result, the Fremantle Football Club board has decided that the Club requires a new coach and new CEO for the 2020 season and beyond,” club president Dale Alcock told the club's website.

“Leadership change is necessary to begin the process of renewal and to set our course for the next 10 years.

"Fremantle had not made the finals for the past four years. This isn’t acceptable to the Board, the players, and most importantly to our supporters. We need high performance and consistency at all levels of the club, so we need to change and evolve.”

Assistant coach David Hale will take control of their clash with the Power this weekend, while COO Graeme Parker will be the interim CEO.
