Harlequins flanker Luke Wallace has signed a two-year extension to his contract, keeping him at the club until the end of the 2014-15 season.
The 22-year-old, who made his senior debut in 2010, scored four tries in 15 appearances as Quins won the Premiership title last season.
Wallace said: "I've progressed greatly as a player since I joined Harlequins.
"The club has an environment that encourages young players to progress and I'm benefiting from that."
He added: "Given the quality of the coaching staff, I have no doubt I will develop further.
"I'm proud to be part of a talented and successful squad and look forward to winning more silverware in coming seasons."
