Jones commits to Harlequins
The contract combines a dual role as player and assistant forwards coach, working alongside incumbent Graham Rowntree.
Confirming the news, Harlequins Director of Rugby, John Kingston said: :Adam has had an enormous impact on the club in his brief time at Harlequins.
"That influence has been both on field, where he continues to do a huge job when called upon, and also off the pitch, where he has set tremendously high standards of professionalism which are providing an inspirational example to others.
"His encouragement to players has manifested itself in assisting the coaching needs of individuals and groups. It is for this reason that, as well as remaining in the playing squad, both Graham Rowntree and I believe it is a perfect opportunity to put him into the role of Assistant Forwards Coach, to help Graham where needed.
"I have no doubt that Adam will continue to prove a terrific asset to Harlequins in his dual role."
The news comes ahead of Big Game 9, when Harlequins face Gloucester at Twickenham Stadium on December 27th.
Jones is one of the most recognisable front row forwards in the game and was awarded the first of his 95 Welsh caps in 2003, against England.
Winning four Six Nations titles, the Abercrave-born tighthead has also competed in three Rugby World Cups and toured with the British and Irish Lions on two occasions; first in 2009 and then on the victorious 2013 tour to Australia.
Joining Harlequins after retiring from international rugby and making 22 appearances for the club to date, he has made an invaluable impact since joining, mentoring youthful talent in the Academy and senior set ups.
Commenting on the announcement Jones added: "I'm delighted to have re-signed with Harlequins and combine my time with the role of assistant forwards coach.
"Since moving to this club, I have loved my time. When John [Kingston] and Graham [Rowntree] suggested the joint role, I jumped at the chance.
"Coaching is a route I have always wanted to go down so this is an opportunity for me to work with two of the best.
"I'd be stupid to not take this chance to develop and up-skill myself with a forward pack that is only going to get better. I'm looking forward to the rest of the season and doing my best to ensure we have a great year."
