St Mirren winger and academy product Jay Henderson has followed striker Eamonn Brophy to Ross County.
The 21-year-old was offered a new deal in Paisley after impressing on loan at Inverness Caley-Thistle in the second half of last season.
That saw him feature in the Highland club's sensational run to the Scottish Cup final, which he featured in against Celtic.
The forward wasn't convinced he'd get the game time he wanted at the SMiSA Stadium this season, with the Scotland under-21 international instead deciding to join the Staggies.
He becomes the second player to make the switch to Dingwall in two days, after former Saints forward Brophy joined the Highland club yesterday afternoon.
St Mirren will receive a development fee, due to Henderson coming through the youth ranks at Ralston and being offered a new contract at the end of last season, and have negotiated a potential sell-on.
Manager Stephen Robinson said: "We made an offer to keep Jay as we wanted to him to stay but he expressed his desire to move on in search of regular first-team football and we can't guarantee that to anyone.
"We have protected the club and managed to get a good fee for Jay with a potential sell-on. We thank Jay for his service to St Mirren and wish him the best in his future career."
