Queen of the South came from behind to stun Partick Thistle 2-1 with an injury-time winner in their Co-operative Insurance second-round tie at Firhill.

Thistle led through Simon Donnelly's first-half opener but substitute David Weatherston came off the bench to score twice.

The hosts went ahead after half an hour thanks to Donnelly's superb 22-yard free-kick, their first shot on target.

The Doonhamers drew level when Weatherston scored with his first touch, drilling a Burns cross high into the net in 64 minutes.

And Weatherston grabbed a dramatic winner in injury-time from another Burns delivery.

Mickael Antoine-Curier scored twice as Dundee cruised to a 4-2 win at Forfar.

Summer signing Leigh Griffiths opened the scoring and Antoine-Curier's double made it 3-0 just past the half-hour mark.

Stephen Tulloch pulled a goal back after the break but and Andy Tod own goal ended any realistic hope of a dramatic comeback before Ross Campbell scored another consolation for the home side.

Three first-half goals were enough to ease Inverness into the third round at the expense of Albion Rovers.

Robert Eagle, Adam Rooney and Nauris Bulvitis all scored before the break before Grant Munro completed a 4-0 rout in the second half.
