Collingwood star Dane Swan rates the chances of continuing his career beyond this season as 50-50.

The 2011 Brownlow medallist is out of contract at the end of the season.

He said on Wednesday his form and how the team performs this year will determine his playing fate.

Swan is 32 and has played 257 games for the Magpies.

He will play more up forward this season, with some pinch-hitting through the midfield.

"I haven't made a decision yet, so at the moment it's 50-50 I guess whether I go on," he said.

"If I'm in the twos by round 18, they won't re-sign me.

"If we win the flag this year I will probably give it away, but that would be the great plan.

"If I can see we're pretty close to a flag, I think I will try and go on."

After a disappointing 2014 season he called "putrid", Swan's form was much better last year.

"It was nice to shut a couple of them (media) up, who said I was finished," he said.

"I can have a great year all I want, but if we don't play finals, which is where the club expects to be ... it's really all for nothing."

Swan has had a solid pre-season and is even spending time in the gym as he tries to help the 'Pies return to the finals for the first time in three seasons.

"I'm actually enjoying the weights I'm doing now, which is weird coming out of my mouth because I didn't like doing them there for about 10 years," Swan said.
