Stefan Martin has signed a three-year contract extension, representing a huge vote of confidence in the Brisbane Lions' future.

The champion ruckman, a joint-winner of this year's Merrett-Murray Medal, had been contracted to the end of the 2016 season - and has now committed to the Club until at least the end of 2019.

The 29-year-old, rated one of the League’s best big men over the past 12 months, has  94 senior games to his name. In 2015, Martin averaged 32.5 hit outs and 21 disposals from 20 matches.

Martin will speak at a media conference later today, with the Lions expected to have more re-signing announcements soon.
