Ally McCoist’s men lost an incredible match at Forthbank to Binos captain Brian Allison’s early goal despite totally dominating the contest otherwise.
The visitors put their opponents under such sustained pressure but despite hitting the woodwork and having an effort cleared off the line, they just couldn’t level.
On a day when they could have gone top of the Third Division with a first away league win of the season, they missed the chance by losing to the SFL’s bottom side instead.
And as home manager Greig McDonald missed the game because he was getting married, it was a new humiliation for the Ibrox side.
Nevertheless, McCulloch is determined in his role as club captain to lead from the front and pick things up – and he maintains it can be done.
The 34-year-old said: “It’s certainly the most disappointing result of my Rangers career. It’s tough to take.
“I thought we weren’t good enough in the first half. I played up front myself and I can’t remember having a chance. We defended very poorly at the goal too.
“In the second we were the much better team but we couldn’t put the ball in the net. We created a couple of half chances but that was it.
“The heads are away down and it’s not a nice dressing room we’ve got just now. The boys just need to get on with it and try to put the result to the back of their minds.
“I wish there was a game tomorrow for us to put things right in and it’s a long time now to our next match.
“We need to roll our sleeves up, stay positive and remember how bad a feeling that was coming off the pitch today.
“While the press are telling us differently, it is still early days in the season and we have only played a few games so we aren’t panicking. We can turn this around.
“There are a helluva lot of points left to play for and a lot of games left and the old saying is that it’s a marathon, not a sprint.”
McCulloch understands and shares the frustrations of the Rangers support, which once again turned out in great numbers to ensure another SFL3 sell-out.
But while he knows they are disappointed with this result, he has asked fans to keep faith in the side and help the team’s emerging players through a tricky spell by encouraging them.
The skipper added: “We need to remember there are a lot of youngsters in the squad who don’t have a lot of experience but have been doing really well.
“This is a reality check and we know we owe the fans after this. We’ve given them a few ups like the win over Motherwell but this is a big downer.
“If the fans can keep a happy medium like the players are trying to do, we will deliver for them.
“We’ve all got to keep encouraging these boys and not let the lads at 17, 18 and 19 go back in their shells again.
“It’s important for me, the other experienced players in the group and the fans to get behind them and help them.”
