St Mirren have brought Kyle McAllister back to the club on loan from Derby until the end of the season.
The winger made 17 appearances for Saints before being sold to Derby aged 17 two years ago but has yet to make his first-team breakthrough.
Manager Oran Kearney told the club's website: "I'm very pleased to have Kyle in. Number one you want to get good players in, but I also think it's very important to have people who have come through the club and know what it is about.
"Kyle had a great start to his career here and got his move to Derby. He's someone I've been aware of since I joined the club with people talking about him. He's fully fit at this point in time and we can't wait to get him in and get him started."
