Blue Richard Hadley, a member of the Brisbane Lions' 2003 premiership team, has announced his retirement after 66 games.

"While the injuries have been very disappointing and frustrating I will always cherish being a member of an AFL premiership side and appreciate how fortunate I am to have had the opportunity to be a part of this," Hadley said.

"I know I will really miss the friendships that have been formed and being a part of the team but believe it is the right time for me to retire from the game."
