Adelaide will be solely led by Rory Sloane in 2020.
Sloane was announced as club captain having shared the responsibility with Taylor Walker last season.
Brodie Smith, Tom Doedee, Matt Crouch and Tom Lynch join Sloane in a new-look Crows leadership group.
Coach Matthew Nicks has full confidence in the selected group to lead the way in atoning for a disappointing couple of years.
“Rory typifies the qualities and attributes that every club wants in its leaders and he was a standout choice as captain, and I am confident we have the right mix of players assisting him,” Nicks told afc.com.au.
“They have a positive influence on others and genuinely care for their teammates, as well as coaches and staff across the organisation, and set elite standards in the way they prepare and carry themselves both on and off the field.”
Adelaide take on Melbourne in their first Marsh Community Series hit out at Casey Fields on February 22.
