Jamaica defender Richard King has joined St Mirren on a two-year deal after leaving Cavalier in his homeland.
The Buddies have an option of a further year for the 23-year-old and say the deal is subject to a medical and visa approval.
Midfielders Roland Idowu and Killian Phillips have formalised moves to St Mirren this summer following loan deals from Shrewsbury Town and Crystal Palace, respectively.
Manager Stephen Robinson says St Mirren have “tracked” King “for a long time and kept up with his progress”.
“He has progressed really well under Steve McClaren and the Jamaican national team,” added the Northern Irishman.
“He’s quick, he’s strong and he’s a project for us as well as it’s a step up in level.”
