Duncan has missed the Swans' two finals victories due to a hamstring strain but will return for the decider against Wagga Tigers at Narrandera Sportsground.

"Yeah definitely. I'm sweet as," Duncan said.

"I could have played two weeks ago but we erred on the side of caution a bit. The boys had a good win the week before so we chose to sit it out.

"I trained the Thursday night before the second semi and it worked out well with the boys winning because it's given me an extra two weeks.

"I would have played on the weekend if we had of lost. I'm good to go."

Duncan, 36, is the only current Swans player to have played in a senior premiership at Griffith, back in 2003.

A seven-time best and fairest winner at the club, Duncan said helping Griffith to their next premiership, some 16 years later would mean the world to him.

"When you're young you take it for granted and think it could happen every year," he said.

"As you get older, you realise the opportunities don't come around that often. This will be my fifth grand final and I've only won the one. Especially being at the back end of your career, you don't want to miss the opportunity that's for sure."

Griffith lost last year's grand final to Collingullie-Glenfield Park by two points. This year the Swans won straight through to the decider and Duncan is certain they are much better placed this time around.

"Without a doubt," he said.

"The difference between last year to this year is that predominantly everyone played last year and didn't know what the day was about. Being there last year, although losing, we know how the day pans out, the crowd, the massive build up and even people coming up in the street to talk about the game.

"We're better positioned. Even with the week off, having two weeks to plan where as last year we only had the week to get our head around it and get ourselves right. We're fit and ready to go. Tigers have got a few injuries and we're all ready to go so there's no excuses."

It is the second consecutive season that Duncan has shaken off an injury concern to play in the decider.

Last year, he suffered a grade one tear to his quad but pushed on to play in the loss to the Demons.

Duncan, a member of Griffith's Team of the Century, has spent most of this season playing across half-back, with a bit of time forward also.

The Swans assistant coach does not mind where he plays on Saturday as he looks to end the club's 16-year premiership drought in the same season he played his 300^th first grade game.
