Andy Coleman admits Dungannon Swifts need a big response ahead of a potentially season-defining five days.
The Co Tyrone side slumped to their first defeat in over a month against Glenavon on Saturday.
It leaves them just two points above the drop zone after Carrick Rangers and Warrenpoint Town won their games.
Dungannon face both teams between now and Saturday in what boss Rodney McAree has described as their biggest week of the season yet.
Tonight, they travel to Carrick for a game which has so far been postponed four times, having originally been scheduled for November.
And Coleman believes the Swifts must put their weekend defeat, which saw Joel Cooper give Glenavon a 1-0 win, behind them.
The goalkeeper said: "We had won four and drew one of our last five before Saturday, which is excellent. Saturday was always going to be tough. We can't allow ourselves to get too down hearted. We won't win every game so we just have to put it behind us.
"It is a big week coming up - it's massive for us, but I know we will go out and give 100 per cent."
Carrick were originally due to host Dungannon on November 7, but the game was called off because of a waterlogged pitch - the first of four postponements for this fixture.
Having managed to finally stage a home game at the weekend - their first since October 31 - both managers will be hoping tonight's clash also goes ahead.
With Warrenpoint also to come, McAree believes it's their most important week to date.
"It has to be, whenever you have to take something from the games," he said. "It will not be easy but we just have to go and address it in the proper way."
