Rangers suffered fresh frustration as Mark O'Hara's double clinched a 2-1 win for Dundee in the Ladbrokes Scottish Premiership at Dens Park.
The Ibrox side – still without a boss a month on from Pedro Caixinha's sacking – missed the chance to move up to third spot as caretaker Graeme Murty's side suffered their second straight defeat.
O'Hara now has four goals in three Dens clashes against Gers after striking either side of Josh Windass' equaliser.
But the Gers faithful let rip at full-time and the Ibrox board can now expect a grilling at next week's AGM unless on why it has taken so long to appoint a permanent manager.
Alex McLeish is the 11/10 favourite in Sky Bet's next Rangers manager market.
Neil McCann's basement boys will celebrate what is just their third win of the campaign.
But there is further to worry about for beleaguered Rangers who also saw forward Alfredo Morelos limp off after colliding with a post.
Post-match reaction
Caretaker boss Graeme Murty insists Rangers' on-going managerial saga is no excuse for their latest slip-up.
"To play for Rangers, you need to be able to motivate yourself, be intrinsically motivated to go and meet the expectations of the football club, regardless of who is in charge," he said after his team missed out on the chance to overtake third-placed Hibernian.
"No disrespect to our opponents, but if we are serious about getting back to the top of Scottish football we need to be winning these games.
"We have had more than enough in both games this week to win them but we haven't executed to a high enough standard, and I include myself in that. We need to be better than we are doing currently. That is not good enough, that is not where we want to be. We need to get better.
"Do the players need a lift from a new boss coming in? They look like a group that need to lift the fans that turn up at Ibrox on Wednesday for a massive game against Aberdeen.
"They need to be ready to put on a show, put on a performance. That is their challenge now. They can't control anything outside of the group. They need to make sure when Wednesday comes they go and execute better than we did today."
Dundee assistant boss Graham Gartland now hopes the victory can prove to be a turning point.
"You hope it's a springboard," said the Irishman. "We have probably played better than that at times this season and not won.
"So the performances have been there and you just hoped the results would follow.
"We showed resilience tonight and to see out the last 10 minutes without giving up a chance was great."
