Murphy has been the captain of the Blues since Chris Judd stepped down from the role in 2013.
Carlton coach Brendan Bolton said Murphy is the perfect man to lead the Blues.
“In 2016, we set about building leadership density across our list. This year, we are sticking to the roadmap and ensuring there is a consistent level of leadership across the board,” Bolton said.
“With only one change to our leadership group for 2017, we are building on the foundations that were set last season. Dennis is a very influential member of our playing group and on the clear vote from his teammates, comes into the spot vacated by Andrew Walker.
“Marc continues to be a tremendous leader for our club and across the past 12 months in particular, has played a vital role in shaping and reinforcing our values and behaviours, particularly working closely with the younger players.”

“Kade, Bryce, Patrick, Sam and Ed are already established leaders at our football club, all finishing in the top five of our Best and Fairest count in 2016 which is a clear indication of them all leading from the front on field too,” Bolton said.
“We know this leadership group will continue to drive high standards for our young playing group as we continue to evolve and grow as a team in 2017.”
