Carlton ruckman Matthew Kreuzer and defender Sam Rowe have both signed contract extensions that will see them remain at the Blues beyond this season.

Kreuzer has signed a two-year extension that will see him through to at least the end of the 2019 season, while Rowe's one-year deal sees him contracted for season 2018.

The 28-year-old ruckman had a career best season this year, and was named in the All-Australian squad of 40 on Monday.

Despite missing out on a place in the final 22, Kreuzer averaged 15.3 disposals, 3.3 marks, 4.5 clearances and 31.7 hitouts per game.

Rowe played the first nine games of the season before rupturing his anterior cruciate ligament against Fremantle in May.

“To Matthew’s credit, he has been elite in his preparation and managing his body throughout the year and working closely with our high performance team which resulted in him playing 21 out of a possible 22 games this year,” Carlton's Head of Football Andrew McKay told carltonfc.com.au.

“He is often referred to as a ‘heart and soul’ player for our Club and we’re delighted Matthew will be remaining in the navy blue for a further two years. 

“Sam has been a consistent and durable performer for us since making his debut in 2013 and has been meticulous in his rehabilitation with his knee injury. The leadership and experience he has brought to our young backline has been invaluable and we look forward to welcoming him back for the start of the 2018 season.

“Matthew and Sam are integral members of the playing group and are both held in very high regard at the Club. We look forward to seeing them continue their careers in the navy blue.”
