Gary Mackay-Steven races on to a ball over the top of the Rangers defence but he takes one touch too many and Connor Goldson blocks his path at the expense of a corner.

Aberdeen are on their heels after a slack pass from James Wilson. Daniel Candeias starts the counter-attack but Michael Devlin is the man in the way again as he blocks Ryan Kent's shot inside the penalty box.

From the Aberdeen point of view, the good thing is they're still in the game. Rangers looked like this in midweek as well, when they had domination but didn't create enough chances. The decision-making and the final ball hasn't been good enough.

The tempo has just dipped a little. Rangers played with a thunderous intensity in a goalless draw against Spartak Moscow on Thursday, while Aberdeen had an eight-day rest before this one.

Could that be a factor?

Joe Lewis takes the pressure of the creaking Dons defence as he confidently clutches a firmly-driven cross from Daniel Candeias.

Ryan Kent and Ovie Ejaria combine well to cut open the Dons defence down the left but the final ball is cut out by the stretching leg of Michael Devlin.

Aberdeen are camped in and around their own box.

Aberdeen beef up their attacking options, sending on Stevie May for Scott Wright.

Lassana Coulibaly is given time and space to meet a dipping corner kick from James Tavernier but the Rangers midfielder sclaffs his volley wide from near the penalty spot.

Aberdeen make a rare foray into the opposition half, win a free-kick, then work the ball back to the keeper. What's that all about?

James Tavernier sends a free-kick harmlessly over after his Rangers team-mate Connor Goldson is flattened by Scott McKenna's late challenge.

Rangers are knocking on the door now and the Aberdeen defence is rocking as Joe Lewis gets down to stop a raking shot from James Tavernier.

Ryan Kent does well to weave his way through a couple of challenges but it's another high, wide and not very handsome long-range shot from Rangers.

Here we go again...

The first half at Murrayfield was pretty honking, so maybe this game will come to life in the second half too.

Andrew Considine has been taken to hospital (there's one pretty much next door to Hampden) and the Aberdeen defender is reportedly doing fine, which is good news after that nasty knock to the face.
