Alex Corbisiero has left Northampton Saints with immediate effect following an injury plagued season.
The 27-year-old played a part in the club's Premiership and Challenge Cup double in 2014 but, in December, announced his decision to leave and take a year away from rugby when his contract expired at the end of the season.
The former British and Irish Lions prop is yet to make an appearance for the Saints this term due to a knee injury that required surgery.
Corbisiero has now been released early by the club, who he thanked for their support during a difficult period in his career.
"I'd like to thank everyone in the Northampton Saints organisation for all of their support on and off the field these last couple of years," he said in a statement issued on the club's official website.
"I've had some amazing highs and some frustrating lows while at Saints but have always been well looked after and supported.
"I've shared some incredible memories and made some great friendships along the way. It has been an honour to be part of such a special group of players and I wish them all the best for this season and the future.
"Lastly, I'd like to thank the Saints' supporters, who have shown me nothing but love. It was a privilege to play in front of them at the Gardens and I will never forget the atmosphere they create and how they rally behind the team week in, week out."
Director of rugby Jim Mallinder shared in Corbisiero's frustrations and wished him all the best for the future.
"Alex has made a big contribution to the Saints, on and off the pitch, and we've all been frustrated that he has not been able to make a consistent run of appearances in the first team," he said. "We wish him success in whatever he decides to do in the future."
