St Mirren's defeat at Inverness allied to Hamilton's win over Hibernian has left Buddies boss Danny Lennon fretting over his team's league survival.
"We've got to get back down to the basics very soon," said Lennon, whose team are three ahead of Accies at the bottom of the Scottish Premier League.
"My players can see that they are playing with a bit of fear.
"I've got to pick them up tomorrow morning and make sure that we are ready for Tuesday against Aberdeen."
St Mirren have gathered a solitary point from a possible 15 in the SPL, a sorry run that includes a defeat by Hamilton in Paisley last weekend.
After their trip to Pittodrie they will finish their league campaign with a match at home to St Johnstone next Saturday.
"If Hamilton made it interesting last week, they have certainly made it a little bit more interesting this week," lamented Lennon.
"I always said they were never out it.
"With that three-point cushion, we've got to make sure that we come out the traps a lot quicker.
"The little bit of momentum that Hamilton have, I feel that they will certainly push us.
"We've got to take care of ourselves. We will analyse where things went wrong for us today."
St Mirren had Michael Higdon, Paul McGowan and Craig Dargo hunting for goals in Inverness but seldom troubled home keeper Jonny Tuffey and paid the price for their lack of goal threat when sub Adam Rooney smacked the winner with five minutes remaining.
Lennon added: "My big message to them today was to go out and be relaxed and concentrate on nothing more than this game.
"I'm very disappointed with the result and with the overall performance.
"It's a very difficult place to come. When Adam Rooney came on he certainly made the difference.
"It's still very much in our own hands but our performances in the last two weeks worry me.
"It baffles me because in training they are fearless, they try things, yet today we looked to be playing a little bit tentative. It's certainly not the message they get from us
"I asked for character today from them. I certainly got commitment but I need commitment along with people who believe that they can go in there with a winning mentality."
