Two-time St Kilda best and fairest winner Sam Fisher has signed a one-year contract extension with the AFL club.

After battling injuries in 2013 and 2014, the 33-year-old defender returned to good form this year, managing 18 senior games to take his career tally to 216.

“We have such a young and exciting group that has worked hard to produce some good, solid performances and I’m really looking forward to seeing their improvement in the future,” Fisher said.
