Former Wales prop Adam Jones will leave Cardiff Blues and join Harlequins at the end of the season.
Harlequins have struggled in the scrum this season, and the signing of Jones would help in that department.
The club sit in eighth place in the Aviva Premiership this season, with only an outside chance of qualifying for next season's Champions Cup.
Jones recently retired from international rugby after failing to make the Wales Six Nations squad. He made 95 appearances for Wales and five appearances for the British and Irish Lions.
