Sydney captain Brett Kirk is weighing up retirement and will make a call on his future this week.
Kirk, out of contract at the end of the season, is set to meet with coach Paul Roos and general manager football Andrew Ireland to discuss the possibility of playing on for a 12th season.
Ireland said it would be left to Kirk, the club's spiritual leader and arguably the toughest midfielder in the AFL, to make the final decision.
"His form has been pretty solid for most of the year but it really is his call,'' Ireland said on Monday.
"We leave it to the older blokes to feel how their bodies are going and I guess mentally whether they are ready to have another crack at it.''
Ireland said the Swans were keen for Kirk, who turns 33 in October, to play on.
"I think it's pretty much his right to continue, we certainly would want him to," he said.
"He'll know his body, how his mind is."
Kirk has been the heartbeat of the Swans since Paul Roos took charge halfway through the 2002 season and implemented the 'Bloods Code'.
While often given a run-with role in the middle, Kirk has generally won more of the ball than his opponents.
He was co-captain of the breakthrough 2005 premiership team and his remarkable consistency has been shown by claiming the best and fairest in '05 and '07 and finishing second in '06 and '08.
"There wouldn't be too many players in the competition with the consistency at that level," Ireland said.
The Swans, out of the finals race this season, have embarked on a rebuilding program now Barry Hall has quit and Michael O'Loughlin will retire at the end of the season.
Veteran defender Leo Barry is almost certain to quit while tagger Jared Crouch is another who could go.
"It has been a really great group,'' Ireland said.
"They have been a very competitive and very resilient for a long term. But you do get to stage where a few move on and you hope the young ones can emerge as well."
"You can you can transition without having to necessarily go right to the bottom of the ladder."
It's understood the Swans could be about $2 million under the salary cap next season, allowing the club to poach a high-profile star.
