Rangers manager Steven Gerrard says his players are suffering from a lack of confidence after losing 1-0 at home to Hamilton.
Connor Goldson was dispossessed by David Moyo, who scored the second-half winner for Hamilton.
The defeat leaves Rangers 13 points behind rivals Celtic in the Scottish Premiership and comes off the back their exit from the Scottish Cup at the hands of Hearts.
It was the fifth time in eight games that Rangers have dropped points and the former Liverpool captain admitted after the game that he has a big job to turn things around.
The only positive over the last few weeks was the win over Braga in the last 32 of the Europa League, which set up a meeting with Bayer Leverkusen in the next round.
Gerrard told Rangers TV: "Again, another mistake has cost us.
"There was an opportunity tonight. Celtic have blinked with one eye but we've blinked with two, which is extremely disappointing.
"We were the better team and created lots and lots of chances but we didn't have the quality to take those. And when that happens, you give the opposition a chance to snatch three points away.
"I didn't think I could be more disappointed than I was after Hearts - but here I am, even more disappointed than I was a few days ago.
"We've got a lot to do - a big, big lot. Myself and my staff are flat because we are doing everything we can. We are trying to change formations and personnel, doing different things in training to try and lift and put confidence into them."
"I have a dressing room that's shot of confidence. We have played ourselves into a rut and I've got a real tough, tough job to pick that up and improve it from here."
The Rangers fans who stayed to the end let their feelings be known when the full-time whistle sounded.
