A fan favourite, Sewell has achieved much in his 10-year career, winning two premierships with Hawthorn and a club best and fairest in 2007 on his way to becoming one of the most respected players both on and off in the field in the competition.
But those achievements didn't come easily for the now 30 year old.
Sewell had to fight for his spot at the Hawks after being originally drafted by the club as a speculative rookie selection in 2003.
Picked up with pick seven overall in the rookie draft from the North Ballarat Rebels, Sewell earned his senior debut just a few months later against Port Adelaide in Round 3 of the 2004 season.
He impressed in that game with 17 disposals (seven contested) and showed glimpses of the gun in and under midfielder he would become with four tackles and three clearances.
He played six matches in his debut season before playing 12 the following year, in 2005.
His breakout year came in 2006 when he finished third in the Club's best and fairest, finishing behind Sam Mitchell and Luke Hodge.
Sewell became one of the game's elite taggers, performing shut down roles on some of the game's best midfielders but what made him such a unique player was that he could win the footy in his own right.
He was a key player in the 2008 Grand Final triumph, winning 27 disposals, five tackles and four clearances.
The midfielder has been a remarkably durable player for the Hawks, playing 19 or more games in each season from 2006-2013. This season has been the first he has experienced some injury concerns, missing 13 games with hamstring issues before breaking into the team again to hopefully make an impact during finals.
He became a dual premiership player last year, playing a key role for the Hawks in the finals series despite some questioning his worth to the team.
Sewell answered his critics with a brilliant finals series as a hard and tough midfielder.
Check out his career in pictures below.

Sewelly with a screamer! Circa 2005. And on the right he shows he always gets the footy out no matter how his opponent tries to stop him.
He sings the song with a very young looking Grant Birchall, Rick Ladson and Danny Jacobs.
He's kicked only 32 goals in his career, here he celebrates one in 2006.
He represented Victoria in the 2008 State Representative game at the MCG and in the same year, was one of Hawthorn's best with 27 disposals in the 2008 premiership win.

This photo sums him up - always first to the ball and relishes the tough conditions.
A diligent trainer, Sewelly is the ultimate profressional on and off the field.
He's a big game player and saved one of his best ever performances for the 2012 Grand Final against Sydney with 33 disposals, 11 clearances and 11 tackles.
He's averaged 21.1 disposals and 4.5 tackles per game across his career.
Who will ever forget that desperation to dive across the boot of Travis Varcoe in the 2011 Preliminary Final to force his kick wide.
In 2013 he became a dual premiership player.
In 2012 injury struck, missing 13 games through injury.
But he fought back and now will play a key frole in Friday night's Qualifying Final against Geelong.
