Hawthorn swingman Tim O'Brien has penned a two-year contract extension with the Hawks, tying him to the club until the end of the 2021 season.

The Hawks recruited the 25-year-old in the 2012 National Draft, and O'Brien has put together his best season for the club thus far in 2019.

Hawthorn recruitment manager Graham Wright said O'Brien had reaped the benefits of his 2019 campaign, gaining the extension after impressing as both a forward and back over the course of the season.

โ€œWeโ€™re excited that Tim has committed to the club for a further two years,โ€ Wright told the club's website.

โ€œWe think he has started to look more and more comfortable at senior level this season and weโ€™ve been impressed by his ability to play as both a key defender and a key forward throughout the year.

โ€œHe is a popular man around the club with a strong work ethic and desire to continually learn so weโ€™re looking forward to seeing how he develops beyond this year.โ€

O'Brien has played 60 games for the Hawks over the course of his seven seasons at the club, kicking 43 goals.

The Hawks still have 18 players off-contract at the end of the season, see the full list down below, as well as each Hawk's contract here.
