Injury has forced Hawthorn's former Melbourne veteran Cameron Bruce to end his AFL career.
The 32-year-old played 234 AFL games over 13 years, but only 10 of those were with the Hawks, nine last season and just one this year, in round four.
A back injury has troubled Bruce for several months and after a scan last week he was advised he risked long-term damage if he played any more games.
Bruce will be used by the Hawks in a coaching role over the rest of the season, an area he hopes to pursue further after this year.
Bruce was the Demons' best and fairest in 2008, along with three other top-three finishes and was part of five finals series with Melbourne.
Bruce thanked those at the Demons who gave him the chance to play AFL football, but said he was keen to stay involved with the Hawks.
"I have made some fantastic friendships and while I walk away as a player today, I will stay involved in this club in any way possible," he said.
Hawks coach Alastair Clarkson said Bruce was the ultimate professional.
"Although it didn't work out as Cameron would have hoped on the field, he has made a significant contribution to our club," Clarkson said.
"We're delighted he is eager to contribute to the team in a coaching or leadership role for the remainder of the season."
