Cyriel Dessers is into the book.

The striker is trying to get onto a knock down and clatters into the back of Luke Graham. That's a very frustrated challenge.

Almost!

Fin Robertson curls a corner to the front post and Ryan Astley fizzes his header just over.

Rangers go up the other end and Djeidi Gassama drills a low shot straight at the keeper.

It's end to end now!

A small applause from Russell Martin. An unlikely victory could be pulled from the fire here.

However, it's a Dundee corner.

There's a delay here, as VAR checks this penalty decision.

The tension in Ibrox is palpable.

Never mind!

Djeidi Gassama gets his legs tangled with Drey Wright.

James Tavernier is on the pitch.

A ball into the box is flicked on by Danilo, but Cyriel Dessers can't get on the end of it. Jon McCracken makes every effort to get there first, and it works.

Higher up the pitch, Emile Acquah holds the ball up well and fires it out to Fin Robertson, who roulettes away from Nico Raskin.

Dundee are the team in control here.

Oliver Antman jinks in from the left and fires with his right, but it's right down the throat of Jon McCracken.

The home fans take the chance to boo, as they react to Dundee's latest attack. Only Nico Raskin's superb tackle stopped Fin Robertson marauding into the box.

48,958 were inside Ibrox at the start of this game.

The vast majority of them supporting Rangers and wondering if their side, down to ten men, can conjure up a couple of goals in the closing 16 minutes or so.

If they don't get a goal, Dundee are leaving here with a famous win.

Not since Ivano Bonetti was the manager, and Claudio Caniggia was in the team, have the Dens Park side left Ibrox with all three points.

Rangers are dominating possession, but they're not able to get a decent break of the ball in or around the box.

The ball sort of sits up for James Tavernier, but he swipes his long-range shot wide.

It's just not happening for Rangers tonight.

Well Rangers fans... what do you think of this then?

Why does this team look so different in Europe? Why do they look a shadow of that team in domestic competition?

Answer at the top of this page please - and keep it clean.

Danilo and James Tavernier are on for Rangers. Max Aarons and Joe Rothwell are off.

There's 22 minutes left and Dundee are taking their time every time the ball goes out of play - and who can play them?

Is this really the same Dundee side who lost to Airdrie and Alloa in the group stage of the League Cup and were two down at home to Hibs inside half an hour?

What a transformation. They're a goal to the good, a man to the good and they've also hit the post. No one can say they don't deserve their lead.

The big question is: can they hold onto it?

Rangers send for more reinforcements, with James Tavernier and Danilo coming on.

Joe Rothwell goes on a rampaging run forward, past three or four defenders and into the box. He runs it too far though, and has to lay it off.

Eventually it comes to Jefte, and it's blocked for a corner.

Ibrox is stunned, but not into silence. They are furious.

You could see it happening.

I'm not sure he meant to bring him down but he did and it is rightly a red card.

Uh-oh. An easy red card for referee Don Robertson to produce.

Defender Nasser Djiga knew it was coming, and was almost turning to walk, like a cricketer who knows he's been caught 'plum'.

Rangers a goal down and now a man down. This will test the patience of both the crowd and the home manager, I fancy.
