Scotland B international Chris Clark has completed his move from Aberdeen to Plymouth for £200,000.
The versatile 27-year-old, who is equally at home at the back or in midfield, has agreed a three-and-a-half year deal at Home Park.
Clark trained with his new team-mates on Wednesday and will go straight into Paul Sturrock's squad for Saturday's league clash with Southampton.
"Chris can play in four or five positions, so it's obviously of great benefit to us that he comes with great pedigree," Plymouth boss Paul Sturrock told the club's official website.
"He's had a long spell at Aberdeen, he really wants to do well, and he will kick on from a fresh start."
Clark recently rejected the offer of a new contract to stay with the Aberdeen, where he made 233 appearances.
