Adelaide Crows veteran Michael Doughty has announced he will retire at the end of the season.
The oldest player on the Crows list, 33-year-old Doughty told team-mates on Wednesday that this season would be his last.
Since his debut with the Crows in 2000, Doughty has played 226 games, ranking him the eighth longest-serving player at the club.
Doughty has missed just three games in the past five years and recently established himself as a key part of the Adeliade back six.
Adelaide coach Brenton Sanderson said Doughty would be difficult to replace.
"While I have coached him for only one season he has quickly become a player I can rely on. Dogga has been a great club man throughout his career," he said.
"He is the typical back-pocket, who puts the team before the individual. His ability to mentor those who will eventually take his place in the side is testament to his character," Sanderson said.
At the start of this season, Doughty, who won best team man awards in 2008 and 2011, took on a mentor role.
