What a day.

Inverness CT join Celtic in the hat for the draw for the semi-finals of the Scottish Cup - to be made on the new BBC Scotland channel on Monday night.

Aberdeen and Rangers will go to a replay at Ibrox on 12 March.

We're back tomorrow for the last quarter-final tie as Partick Thistle host Hearts at Firhill. That will also be live on BBC One Scotland.

Thanks for your company. Highlights of the Scottish Cup ties on Sportscene later. Cheers.

Dundee United boss Robbie Neilson: "Bitterly disappointed, I thought when we got ourselves back in the game with the goal we were in the ascendancy and then we got done by a long-throw at the end.

"Really disappointed but what we’ve got to do now is go and win the league. That’s it. The Scottish Cup is done, it’s all about the league for us now.

"You never want to go out of the cup at this stage, especially against Inverness at home after such a good turnout from the crowd. We’ve let them down so we need to make sure we repay them with a win next Saturday.

"As you can see there’s still a long, long way to go with this football club but we are on the right track. There’s a positivity about the place. Yes there was negativity today because of the result but we need to keep pushing on and try to get out of this league."

Paul Kelly: Great game of football.

Inverness CT boss John Robertson: "The boys are raging - they're really upset with the referee [over the penalty] they think it's a foul for us first.

"They then think Paul McMullan has gone down easily.Then, it's a borderline offside [Nathan Austin's header] and it looked like it was going to be a replay.

"But Aaron Doran is brilliant, he pops up and gives us a win that I don't think anybody could really disagree with. It was a well-deserved win."

Joe Chalmers speaking on BBC Sportsound: "I was due one, it's my first of the season and I picked a good time to get it! It was a tough match but we definitely deserved the win.

"Going to Hampden is going to be special, you always hope you can go on a cup run and, being in the Championship, you're not sure if you're going to do it but it's a special moment for everyone."

Inverness CT boss John Robertson on BBC Scotland's Sportscene: "I thought we thoroughly deserved it today, Right from the start, we changed the tactics, played a system that suits us well.

"Joe Chalmers was magnificent - what a goal! Then he's hit the bar.

"United didn't really hurt us in the first half."

Aaron Doran on BBC Sportsound: It's unbelievable, it's brilliant from the lads, and I think we deserved it over 90 minutes.

I didn't see much of the penalty but I saw a lot of the lads running over so I'm not sure if it was a dive or not, but we kept going and got what we deserved.

The official Inverness CT account tweets a picture of Hampden with the message: "See you soon"

BBC Sportsound pundit John Hughes: We mentioned that Aaron Doran could be the match-winner at half-time but I didn't expect him to win it like that. He's not renowned for his heading ability but he's got the goal to put Inverness in to the semi-final. What a horrible way to lose the match for Dundee United.

There's nothing like a last-minute winner - if it's for your team. The visitors are in jubilant mood; Dundee United keeper Benjamin Siegrist sits on the turf. Stunned.

Inverness CT boss John Robertson gallops down the touchline to celebrate in front of the visiting supporters. In sharp contrast, United's players and fans look on, stunned.

The romance and heartache of the Scottish Cup.

Three minutes of added time at Tannadice.

Much huffing and puffing but, understandably, neither side wants to make a mistake on the cusp of full-time and a replay.

Four minutes remaining at Tannadice - are we destined for another draw and another Scottish Cup replay?

Inverness CT have a late winner. No, scrap that. An offside flag cuts short substitute Nathan Austin's celebrations after his looping header found its way past man-mountain Benjamin Siegrist.

Replays show Austin was offside... just.

Jim Spence: Wee Robbo needs to get back on the sunbed.....looking a shade peely wally

BBC Sportsound pundit John Hughes: Dundee United have been much improved in the second-half. They were a bit flat in the first-half but they've been more than a match for Inverness in the second-half and they could easily go on and get the goal that wins this cup tie.
