Carlton ruckman Matthew Kreuzer has put pen to paper on a contract extension, signing on for the 2020 season.

The 30-year-old has played 183 games for the Blues since joining the club as the number one pick in the 2007 AFL Draft, and is thrilled to be signing on with the Blues.

“I’ve been here my whole career and this place is like a second home to me. It means a lot to say that I’m a one-club player at Carlton,” Kreuzer told the club's website.

“The Club has shown great faith in me throughout my career, the supporters have been incredible to me and I am motivated to repay the faith and help this playing group achieve the success our supporters deserve.”

“I’m looking forward to the team having a strong finish to the year and running out in the Navy Blue again next season.”

The ruckman has played 10 games this season and is averaging 29.6 hitouts, the second-highest average of his career.

“Kreuz is a ‘heart-and-soul’ player of this football club so we are really happy to see him remain at the Blues,” Carlton's General Manager of List Management and Strategy Stephen Silvagni told carltonfc.com.au.

“His work ethic, resilience and determination make him important to the progression of this group.

“Kreuz is held in very high regard at the Club and is a daily example to our younger players of what it takes to earn your career at the elite level.”
