Crows veteran Richard Douglas is set to call time on his AFL career at the end of this season.
The 32-year-old is the second Crow to announce their retirement this week following defender Andy Otten's announcement on Tuesday.
Douglas' 246th game this Sunday against the Western Bulldogs could be his last, with the Crows needing to win by five goals and hope other results go their way to have a chance of making the finals.
With 164 AFL goals and the 2010 Malcolm Bright Medal, Douglas is one of only 16 players to reach 200 appearances for the Crows and ninth on their all-time games played list.
Speaking to the club website Douglas said, "From a football perspective, there has been so many great times but it is the people and the lifelong friendships that are the real highlights."
"I arrived at the club as a teenager and the many people past and present who make it such a special place have played a significant role in shaping the person I am today."
"I'll miss the day-to-day things that come with being part of a professional footy environment but I am also excited about the next phase of my life."
Adelaide's head of football Brett Burton said Douglas would be remembered as one of the club's most reliable and durable performers.
"Richard is a class act both on and off the field and his achievements and longevity in the game are a testament to his talent, work ethic and willingness to put the team's interests first," said Burton.
"He has always shown genuine care for his team mates, coaches and staff and it is one of the many reasons why he is such a respected and popular figure in our Club. We wish he and Alessandra all the best for the future."
