DOB: 28 December 1991
From: Ormond/Sandringham Dragons, Selection 34 2009 National Draft
Games: 99* (to end 2018)
A 207cm ruckman, the tallest ever to go through the AFL draft camp, Gawn missed the Under 18 championship due to a knee reconstruction but was snapped up by the Demons in the hope that his size and mobility would make him a weapon similar to Fremantle's Aaron Sandilands.
Debuting midway through the 2011 season in the absence of an injured Mark Jamar - becoming the fourth tallest AFL player on record - Gawn impressed in four matches but with Jamar returning he found it hard to break into the side again and played out the year with Casey.
Gawn suffered a knee injury during a training session in December 2011 and was forced to undergo surgery which kept him out of the 2012 season. He returned in 2013 with some encouraging performances, but was often used primarily as a forward.
A hamstring injury delayed Gawn's 2014 campaign, and when he returned he again played as an understudy to Jamar or as a forward. His season ended prematurely in the second quarter of the Round 23 match against North Melbourne when he suffered another knee injury.
After struggling to break into the senior side in 2015 he eventually made the first ruckman job his own, forcing Mark Jamar out of the side and playing the rest of the season. In 2016 he played every game, being named the All Australian ruckman.
His 2017 season was temporarily halted by a serious hamstring injury suffered early in the season, he played just 13 games. In 2018 he returned to play every game for the season, breaking the AFL record for the most hitouts in a season and being named All Australian for the second time.
