There are two massive matches in the SPFL on Friday evening, with games at Tannadice and The Energy Check Stadium at Firhill.
It's the second leg of the Premiership play-off quarter-final on Tayside, with Dundee United taking on Dunfermline Athletic after a 0-0 draw at East End Park on Tuesday.
There is no away goals rule in the play-offs, so extra time and penalties, if required, will settle the outcome if the scores are level on aggregate. The winners take on Livingston in the semi-finals on Monday and Friday of next week.
In the Ladbrokes Premiership, the bottom two meet at Firhill, live on BT Sport at 7.45pm. Partick Thistle, in 11th place after a 1-1 draw at St Johnstone last time out, are two points ahead of Ross County, who lost 2-0 at Hamilton Accies on Saturday.
