Clitheroe were made to pay for being unable to hold onto leads over the week.
On Tuesday night, the Blues drew 1-1 at Mossley, having led for 70 minutes.
And on Saturday, Paul Moore’s men saw a two-goal advantage slip through their fingers as Darlington 1883 came back to win 3-2 at Shawbridge.
At Mossley, a draw was a fair result.
The first period burst into life when a clumsy challenge on 15 minutes from makeshift left back Will James saw the referee point to the spot. However, the resulting penalty kick was ballooned over the bar.
A minute later, a through ball from Rob Bodie to Paul Carney saw the Mossley keeper block at his feet, before Clitheroe took the lead on 19 minutes as Chris Dykes hit a screamer from 25 yards from a ball which had been pulled back from the left.
Minutes later an Adam Birchall deflection skimmed the post, but the Blues went in ahead.
The second half saw Clitdefend progressively deeper. The hosts hit the post on 55 minutes, and 15 minutes from time Mottram made a point blank save from a thunderous shot.
The brave Clitheroe resistance was broken in the first minute of injury time when a peach of a strike from Daniel Broadbent arrowed into the corner.
It was a solid display by Clitheroe with many players playing out of position, not helped by Scott Bakkor pulling up with an injury during the warm up.
On Saturday, Clitheroe just fell short in an entertaining game against a strong Darlington side despite a spirited and battling performance.
The Blues raced into a two-goal lead thanks to a tap-in from new signing Jamie Campbell, who pounced when a header from a corner was parried by the keeper, before Bakkor beat the off-side trap, chested the ball down and drove the ball under the keeper from an acute angle.
Darlo responded well and put Clitheroe under pressure.
Eventually the pressure paid off, nine minutes from time, as the ball was smashed home by Amar Purewal from 10 yards with Mottram having no chance.
This lifted the visitors and they got a second at the death from a poorly defended corner, with Purewal again on target.
And Darlington snatched an injury time winner as Andrew Johnson latched onto a great pass into the box and lashed a shot into the far corner.
But Clitheroe could hold their heads high after a performance which suggests they will win more than they lose.
