Carlton star Matthew Kreuzer has extended his contract, as has defender Sam Rowe.
Kreuzer has agreed to a two-year extension, taking him until the end of 2019.
Rowe has signed a one-year extension.
Carlton head of football Andrew McKay praised Kreuzer, who made the All-Australian squad of 40 this season.
“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,” he told carltonfc.com.au on Thursday night.
“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."
Rowe, who ruptured his anterior cruciate ligament in May, has been crucial for the Blues, finishing equal sixth in the best and fairest last season.
“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," McKay said.
“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.”
