Dundee made four changes from Saturday as they switched to a formation with four at the back. Aaron Donnelly, Mo Sylla, Scott Tiffoney, and Seun Adewumi came in for Antonio Portales, Clark Robertson and Seb Palmer-Houlden who were injured, and Fin Robertson, who was on the bench.
The game started slowly for Dundee, in fact both teams struggled to get going in the first 10 minutes. Motherwell looked more dangerous when they attacked.
But 2 minutes later Motherwell took the lead from a corner Casey headed home totally unmarked six yards out. It was dreadful defending, and has been for spells during this season.
Dundee continuted to struggle, ane the few moves over the half way line failed to test the Motherwell defence.
Jon McCracken had to punch over a fierce 18 yard shot from Slattery was the only real effort on goal before half-time.
Dundee started the second half and looked much better going forward, then after seven minutes Joe O’Shaughnessy came on as a straight replacement for Ryan Astley.
Motherwell worked hard to deny Dundee time or space on the ball, but at least they kept at it.
After 71 minutes Charlie Reilly replaced Scott Tiffoney, playing wide on the right. Dundee had their best spell of the match pinning Motherwell back and keeping the home side under pressure. For all the Dee’s attacking, however, Well held firm and the Dark Blues couldn’t get a shot on target or even have any close misses.
But after 79 minutes the dark blues got the break through when a long ball from O'Shaughnessy put Reilly in the clear and he knocked the ball a few yards to Simon Murray to score a vital goal.
It was a real boost for the team, but sadly just 5 minutes later Motherwell scored what proved to be the winner. After a few attacks which Dundee failed to clear Casey to volley home 12 yards for his second goal of the night.
It was hard one to take, Dundee did attacked but never got close enough to force a draw. Both teams were pretty poor tonight with Motherwell slightly better in the first half.
A big game on Saturday as Dundee play St Johnstone at Dens Park. It's one we to need to win just to keep the gap from bottom place,
