England flanker James Haskell will leave Wasps when his current deal expires at the end of the season.
The 32-year-old, who has won 75 caps for his country, is "considering his future options prior to announcing his next career move".
"I have had a fantastic career at Wasps and would like to think I have played a part in the club's success over the years," said Haskell.
"I am looking forward to the next phase of my career. I wish all the players and officials at Wasps all the best for the future and will give my usual 100 per cent for the rest of the season."
Haskell made his Wasps debut against Harlequins in September 2003 and was part of the Premiership and European Cup-winning sides before departing in 2009 for spells in France, Japan and New Zealand.
He rejoined Wasps in 2013 and had a stint as club captain. He has made 194 appearances for the Coventry side, scoring 21 tries.
"Hask goes back a long way with Wasps," said Wasps director of rugby Dai Young.
"Since starting in the academy as a teenager he has played around 200 games including a spell as club captain, which is a great achievement.
"I have no doubt whatsoever, given his character and loyalty to this club, that he will remain fully committed until the end of the current campaign.
"On behalf of everyone at Wasps I'd like to thank James for his efforts and wish him well for the future."
