Walker has agreed to a contract extension which keeps him at West Lakes until the end of 2021, at which time he will be 31.

The big forward is among a number of players already committed this year, including Eddie Betts, Wayne Milera, Reilly O'Brien, Luke Brown and Kyle Hartigan.

Voted by his peers as the competition’s best captain last year, Walker has played 142 games and kicked 336 career goals.

He joined the Crows as a New South Wales Scholarship selection and made his AFL debut in 2009.

“Like I have said many times before, I love the footy club, its people and especially my teammates,” Walker said.

“I am convinced this playing group can achieve the type of success we all crave and the supporters deserve.

“It will take sacrifice, everyone focusing on what is best for the team and plenty of hard work but I know the boys are up for the challenge.”

Crows Head of Football Brett Burton praised Walker for the manner in which he approached the recent negotiations.

“Tex is an influential leader and an important person around our Club,” Burton said.

“He is also one of the competition’s elite forwards and continues to mature as a footballer, leader and person.

“His willingness to commit, in a way that assists the Club in keeping this group together, highlights his faith in where we are heading and his team-first approach.”
