Sydney Roosters captain Jake Friend has announced his retirement from the NRL, effective immediately.

Friend informed teammates and close friends of his decision to call-time on his 264-game career earlier this week, with the club making an official announcement on Thursday.

The Queensland playmaker has faced a long battle with concussion and head trauma, suffering his third concussion in the past six months alone following a head knock against Manly in Round 1.

Friend made his debut for the Tri-colours in 2008 and won three premierships during his time in Bondi.

The 31-year-old made his Origin debut last year for the Maroons and also earned caps for Australia and the World All Stars.

In a statement published to the club's website, Friend sent out a heart-warming message to his fans and friends following his decision.

โ€œI was 15 when I joined the Roosters and have loved every minute of the journey.

โ€œThere are so many people who have played an important role in my career, and I would like to take this opportunity to thank them all.

โ€œI canโ€™t thank the Roosters staff enough, especially Cathy King, Craig Fitzgibbon, Travis Touma, my teammates Mitch Aubusson, my roomie Jared Waerea-Hargreaves and my manager Steve Gillis who have been on this journey with me since day one.

โ€œI would also like to take the opportunity to thank all the sponsors, members and supporters of this great club.โ€

โ€œI also want to make a special mention of Trent Robinson. Trent is the best coach Iโ€™ve ever had, and Iโ€™m a better player and man for the last 11 years Iโ€™ve known him. To our coaching and support staff, thank you for setting the bar every day.

โ€œIโ€™ve played with some pretty special people here at the Roosters over the years, many Iโ€™m proud to call my closest friends, and Iโ€™d like to thank them. To my current teammates, itโ€™s been an honour to play alongside you and to be your captain."
