Rangers captain Lee McCulloch admitted the 1-0 defeat at Stirling Albion was the lowest moment of his career at Ibrox.
The Light Blues are still searching for their first away league win of the season after Brian Allison's solitary goal gave Stirling only their second victory of the season.
And a bitterly disappointed McCulloch told the club website: "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.
Gers boss Ally McCoist fully expects a response from his players following this dismal result.
"Everyone here has a responsibility, every individual within the playing and coaching staff has that but none more so than my own," he told Rangers' website.
"I know the responsibilities and the job in hand and I'm all the more determined. We lost a league game and as much of a blow as it is, I'm very confident we'll bounce back."
