Dumbarton 2-1 East Fife
Darren Young admitted his side fell well below standards in their 2-1 loss to Dumbarton on Thursday.
Goals from Ryan McGeever and Adam Frizzell gave Sons the win with Ross Dunlop netting a late consolation in the closing seconds.
Boss Young was frustrated with the defeat, which came on the back of a decent performance on Tuesday against Partick Thistle.
But with the side now coming to the end of a gruelling run of fixtures, the manager believes his squad may be starting to feel the effects.
In the aftermath of the loss the manager said a few opinions were exchanged before a line was drawn under things and the side looks ahead to visiting managerless Forfar on Saturday.
Young said: "It was poor, very, very poor.
"We made nine changes, a lot of boys were struggling a wee bit and we were trying to protect them.
"Maybe it was a game too far.
"We've had a good chat with the boys, a lot of things were aired and opinions came out.
"It doesn't help when you're up against a big team and you go and lose a goal after two minutes.
"That puts us on the back foot and then in the second half we didn't create too much."
Young will be hoping his side bounce back at Station Park tomorrow as they aim to muscle in to the top four.
Forfar will go into the game without their manager and his assistants after Stuart Malcolm, Martyn Fotheringham and Barry Sellars stepped down on the back of their 3-0 loss to Clyde on Thursday.
