Lewsey missed the World Cup final in 2007 because of injury
Josh Lewsey has agreed a one-year contract extension with London Wasps with his deal with the club now running until the end of the 2008/2009 season.
England's Lewsey has played at centre, wing and full-back for Wasps and is currently in his testimonial year after 10 professional seasons with the club.
"The club has made some major developments in the last year both on and off the field," said Lewsey, 31.
"I'm very pleased to be staying at Wasps for a further season."
Lewsey initially joined Wasps at 18 but his studies at Bristol University saw him switch to the west country outfit.
He spent two seasons at Bristol before moving to Wasps in the summer of 1998.
Wasps director of rugby Ian McGeechan said: "I'm delighted that Josh has agreed to extend his contract with Wasps.
"He has been in outstanding form for us since returning from the World Cup, and to have a player of his calibre, experience and enthusiasm in the Wasps squad is a huge positive.
"Josh is a good role model for any rugby player, and as well as being a key figure in maintaining our continuity going forward, he will have an important role to play in developing our younger players to their full potential."
