No goals in the opening 10 minutes at Tannadice but Inverness CT have gone close a couple of times.

BBC Sportsound pundit John Hughes: "It's an even game at the moment, the two sides are still sparring and feeling each other out."

Inverness CT come close to breaking the deadlock, firstly through a raking Aaron Doran shot and then Coll Donaldson with a bullet header from the resulting corner but Dundee United keeper Benjamin Siegrist is equal to the task on both occasions.

Dundee United don't look shy about going long in the early stages. A long diagonal finds Fraser Fyvie but Inverness CT managed to nullify the threat.

A cracking atmosphere for the second of our Scottish Cup quarter-final ties this afternoon.

W'e're under way at Tannadice.

Hit the play button on our live page to watch BBC One Scotland coverage of the cup tie at Tannadice, with live commentary from Liam McLeod.

Former Aberdeen defender Willie Miller on Sportsound: They were evenly matched throughout the game. Andy Considine's header - he just took his eye off it and lacked the concentration. That was the big moment for Aberdeen. Rangers were always a real threat on the break, though.

At the end of the day, it was a very tight affair, a decent game of football which always kept your interest. Not a classic, it ends in a draw and I don't think anyone is surprised.

Managed to catch your breath? Good, we'll turn our attention to our second quarter-final today, as Dundee United host Inverness CT.

It's live on BBC One Scotland - why not watch it and stay with us for live text coverage, too? A bit of multi-tasking on a Sunday afternoon.

Reaction from Pittodrie as and when we get it.

Dundee United beat Inverness CT 1-0 on Tuesday evening, and the sides meet again at Tannadice this afternoon.

From that midweek clash, United make two changes. Calum Butcher and Paul McMullan drop out, with Cammy Smith and Fraser Fyvie coming in.

Peter Pawlett was ordered off in midweek for two yellow cards, but is able to play.

The visitors make three changes. Shaun Rooney, Kevin McHattie and Nathan Austin are replaced by amie McCart, Carl Tremarco and Aaron Doran.

Fortrose Academy pupil Lewis Hyde, 16, is on the ICT bench.

Handshakes, applause and looks of disbelief all around Pittodrie. A cracking Scottish Cup tie; both sides will have to do it all again in a replay at Ibrox on 12 March.

One minute of added time - time for someone to make themselves a hero before their Sunday steak pie?

Former Rangers midfielder Neil McCann on Sportsound: "If Aberdeen are a little bit more aggressive in their play and take a few risks, Rangers are showing they're so dangerous on the break."

Another Rangers chance, this time Aberdeen defender Scott McKenna flies across the box to nullify the threat of Alfredo Morelos.

Corner to the visitors. From the subsequent set-piece, Morelos fires a shot at goal, brilliantly blocked by the diving Andrew Considine. A Saving Private Ryan-style block from Considine - that looked a certain Rangers winner.

Steven Gerrard will be going bananas. Daniel Candeias brings a promising counter to a shuddering halt after being caught offside.

The visitors broke after an Aberdeen attack but Candeias failed to look across the line before collecting a through ball.

Former Aberdeen defender Willie Miller on Sportsound: We've seen Allan McGregor do that on so many occasions, such a vital save from him. Rangers haven't defended too well, the two centre-backs have been found wanting, they haven't been strong enough and they haven't been up for the fight.

We're into the final 10 minutes. The Scottish Cup tie is finely poised: are we set for a late, late winner? Or is a replay at Ibrox in the post?

Referee Kevin Clancy has more names in his black book than his autobiography - should he ever decide to pen one - as Max Lowe is shown the well-worn yellow for a foul on Ryan Jack.

Pinball in the Rangers penalty area continues as firstly Andrew Considine then Scott McKenna are denied. Allan McGregor continues his recent superb form for Rangers.

Moments later, the visitors pin their ears back and thunder forward on the counter. The ball is played into the feet of Alfredo Morelos, but the Colombian is flagged offside.

Breathless stuff at Pittodrie.
