The Cardiff Blues academy product returned to his home region in 2016 for a second stint following a seven-year spell with Saracens.
Gill came through the ranks at Cardiff Arms Park and made his regional debut against Munster in 2006, having impressed for Cardiff RFC.
The Wales Under-18 and 20 international continued to impress but saw opportunities limited by the presence of Gethin Jenkins.
Gill was signed by Saracens in 2009 and quickly established himself as a first team regular.
During his time with the English club, Gill broke into the Wales senior set-up and won his first cap against Ireland in 2010. The prop also played a part in the 2012 Grand Slam, starting in the opening victory over Ireland at Aviva Stadium.
At Saracens, Gill picked up three Aviva Premiership-winning medals and also lifted the European Champions Cup in his final season at the London-based outfit.
The former Ysgol Gyfun Cymer Rhondda pupil reached the 50 appearances mark for Wales’ Capital Region during the 2018/19 campaign.
