Harlequins prop Mark Lambert has signed a new contract, which will keep him at the club until the summer of 2017.
The 30-year-old came through the south-west London club's academy and has made 161 appearances for Quins since his debut in 2004.
"To sign a contract which takes my time at the club to at least 14 years is something of which I am incredibly proud," he said.
"I look forward to playing my part as we work for future successes."
Lambert has represented England at Under-19 and Under-21 level and has previously been called up to the England Saxons squad.
"For me Mark is everything this club is about," Quins director of rugby Conor O'Shea said.
"On the pitch he is an outstanding competitor and off the pitch he works tirelessly. He is one of our most important re-signings."
Lambert has played 16 games for Quins this season and scored two tries.
