St. Johnstone have completed the signing of former Newcastle United youngster Marcus Maddison.
Durham-born winger Maddison was one of four teenagers to leave St. James' Park by mutual consent earlier this month, but has joined the Scottish Premier League side following a successful trial.
The 19-year-old, who scored three times in ten Barclays Under-21 Premier League appearances this season before his departure, has signed a deal until the end of the season.
Magpies midfielder Mehdi Abeid is on loan with the Perth outfit until the summer.
