Saracens have announced the signing of Northampton Saints' Calum Clark, who will begin a three-year deal at the start of next season.
The one-cap England flanker, who joined the Saints in 2010, has endured some injury woes of late, but is relishing the prospect of joining the Premiership and European champions.
"I am very fortunate to have played for a great club like Northampton," the 27-year-old said in a statement on Sarries' website.
"I've had a difficult 18 months on and off the field and I feel like I need a new challenge.
"I feel very privileged to have been given an opportunity at Saracens. They are always a difficult side to play against and I'm looking forward to taking on a new environment and getting a fresh start in the summer."
Sarries have already secured the services of Toulouse hooker Christopher Tolofua and Wales international Liam Williams for next season, leaving director of rugby Mark McCall content with his transfer business.
"We're very happy to secure Calum's signature, along with Liam's and Christopher's, as we continue to build for the future," said McCall.
"We have identified a handful of players who we felt would improve what is now a stable, successful and developing squad and we're delighted to have been able to wrap up these signings for next season."
