Watch : St Johnstone and Dundee square up with Premiership status on the line
Bosses rally their teams ahead of "6 pointer"
McDiarmid Park in Perth will be no place for the faint-hearted tonight as St Johnstone, sitting at the foot of the table, lock horns with 2nd bottom Dundee. It certainly adds spice to a tasty Tayside tussle.
Saints are on a real low after Scottish Cup humiliation at the hands of Kelty Hearts made it TEN defeats in a row. Can Callum Davidson lift his men for this crucial clash ?
St Johnstone could have new signing John Mahon in their squad, but the Irish defender is not ready to start.
Callum Hendry has been recalled from a loan spell with Kilmarnock and Cammy MacPherson has signed from St Mirren after being briefly recalled by the Paisley club from a loan spell in Perth.
Midfielders Craig Bryson (ankle) and David Wotherspoon (knee) are long-term absentees while Michael O'Halloran (hamstring) drops out and Callum Booth is a doubt.
Dundee were also in the doldrums following 6 defeats on the spin, but their weekend cup win over Dumbarton lifted the gloom, so they'll be desperate to build on that.
The Dark Blues have the chance to turn the screw on their rivals with a victory - but can James McPake's men take that chance ?
Dundee could hand Niall McGinn a debut after signing the 34-year-old winger from Aberdeen.
Canadian midfielder Jay Chapman is also in line for his first appearance after arriving in Scotland.
Jordan Marshall will miss the match through injury while Cillian Sheridan (Achilles) and Lee Ashcroft (hamstring) are long-term absentees.
