England prop Joe Marler has committed his future to Harlequins until at least 2016, the Aviva Premiership club have revealed.
The 23-year-old academy graduate will make his 100th appearance for Quins against Stade Francais on Friday.
Harlequins Director of Rugby, Conor O'Shea is confident Marler will be a pivotal figure at both club and international level for some time to come.
O'Shea said "We are obviously delighted that Joe has committed his future to Harlequins. It is incredible to think that at just 23, he will make his 100th senior appearance this Friday.
"He is, and will continue to be, a corner stone in the pack and in the success of this club. Joe is developing into one of the leading loose heads in international rugby.
"Joe still has so much more to give and like us all, is hungry for more silverware for both club and country.
"I am really excited, as I'm sure the Harlequins supporters will be, to see Joe's continuing development in the coming years in a quartered jersey."
Meanwhile, Marler is delighted to be given the opportunity to repay the faith the London club showed in him.
"I am really happy to have signed on again with my childhood club, Harlequins," said Marler.
"When I was given the opportunity to re-sign for the club, there was never any doubt in my mind that this is where I wanted my long term future to be."
