St Kilda veteran Sean Dempster will play on into a 13th AFL season, after signing a one-year contract extension.

Dempster, 32, showed no signs of slowing down this season, ranking in the top five at St Kilda for marks, one percenters and disposal efficiency.

Saints CEO Ameet Bains said the club is thrilled to have Dempster's experience at the club for another season.

“We’re thrilled to have Sean sign on for next year after another consistent season in 2016.” Bains told Saints.com.au.

“Sean leads by example with his impressive approach to training and preparation and he has been extremely reliable and durable over the years.

“With his level of experience, Sean will remain a strong presence down back and will continue to mentor our younger players and assist in their development.”

Dempster said he is looking forward to helping the young group develop after an impressive 2016 season.

“I’m really happy to have signed on for another season with the Saints after what’s been an exciting year on and off the field.” Dempster told Saints.com.au.

“We’re starting to see some reward for our efforts but we know that we’ll need to put in a lot of hard work if we want to take the next step in 2017.

“I’m enjoying football and my body feels good so I’m looking forward to being able to play at a high level next year.”
