Dundee manager Barry Smith has told his players they cannot afford to dwell too long on their shock Scottish Communities League Cup exit at the hands of Queen's Park.
The Tayside club became the fourth Clydesdale Bank Premier League scalp of the second round as they slumped to a 2-1 defeat against the Irn-Bru Third Division side.
But with a tough visit to Hearts looming when they return to league business this weekend, Smith insists Dundee must move on quickly from the cup disappointment at Hampden.
He said: "We just have to dust ourselves down and get on with it.
"We've got a big game on Sunday and we must move on quickly and make sure that we're ready for Sunday's game."
Kilmarnock, Hibernian and Ross County were all dumped out by lower league opposition on Tuesday night and Queen's Park head coach Gardner Speirs believes the results in the cup have shown there is talent outside the top flight.
He said: "A couple of teams had good results against SPL teams last night and this is a smashing result for our guys and the club.
"There are some good teams and good players in the division.
"There has been a lot of talk lately that maybe that wasn't the case but players who are determined and ambitious will always try to prove their quality.
"Dundee have got SPL players, they are a good side. Tonight we have acquitted ourselves well and taken advantage of the circumstances that came our way."
