Olly Kohn has committed his future to Harlequins by agreeing a one-year extension with the London outfit.
The 31-year-old, who joined from Bristol in 2006, will now remain with the club until at least the end of the 2013-14 season.
"I am very honoured to sign up again at a great club with a great group of players who share a real ambition for further success. More exciting times lie ahead I'm sure," he told reporters.
Harlequins director of rugby Conor O'Shea added: "There is no better bloke you could wish to meet in rugby, however, on the pitch there is none more physical when it comes to what the game of rugby is all about.
"He has developed so much in his game over the last number of years and is comfortable on the ball, and when it comes to the scrum and maul, he is the go to man. We are delighted to have Olly on board and hope this is where he will play for the rest of his career."
Kohn has made 134 appearances for the club.
