Transfer day round-up
New faces at St Johnstone and Dundee United, and a departure at Dundee on deadline day.
St Johnstone signed Peterborough striker Joe Gormley on loan until January.
Dundee released 20-year-old Andrew Black but manager Paul Hartley is still looking for two players.
Dundee United fought off strong competition to sign Norwich midfielder Tony Andreu on loan.
It comes after Utd boss Ray McKinnon brought in two players earlier this week, defenders Frank van der Struijk and William Edjenguélé on one year contracts.
