It's all kicking off and Panutche Camara is given his marching orders!

It starts with a bit of afters between Craig Halkett and Owen Stirton. Camara gets involved and clashes with Marc Leonard before being shown a straight red card by the referee.

Coach Dave Bowman has also been shown a red card in the aftermath.

Derek McInnes is making a triple change.

Claudio Braga, Jordi Altena, and Harry Milne are off.

Jamie McCart, Michael Steinwender and Sabah Kerjota are introduced.

Here comes Owen Stirton for United, he replaces Nikolaj Moller for United.

Wow!

Ashley Maynard-Brewer makes an impressive double block to deny Pierre Landry Kabore. The first was blocked by his foot then, while still on the deck, he's get a leg in the way of the rebound.

The new man proving why Jim Goodwin wanted him to be number one.

That's a massive moment in the game.

If that goes in, the energy of the stadium changes.

That's United's best chance of the game.

Panutche Camara races forward and plays a lovely cross in to Zac Sapsford who heads wide.

Hearts are pretty comfortable, as you would expect against their ten-man opponents.

But boss Derek McInnes may be disappointed his side haven't capitalised more on the extra man advantage by further extending their lead so far in this second half.

Here comes that United change too - Camara on, Sibbald off.

Hearts are doing everything right here, apart from finding the back of the net.

Claudio Braga is waiting for the pass inside the United box but gets the ball tangled with his legs and can only bundle it out for a goal kick.

Looks like Sibbald is going to be making way for Panutche Camara very shortly...

Craig Sibbald hauls Alexandros Kzyiridis to the ground as Hearts push up in numbers.

The referee lets the attack fizzle out before booking the United man.

United hit Hearts on the counter-attack but they're light in numbers. Zac Sapsford has a pop from the edge of the box but it's an easy save for Alexander Schwolow.

Pierre Landry Kabore dances into the box, he loses the ball but it falls to Harry Milne on the right who floats in a cross. Tomas Magnusson gets a head to it but can't keep his effort.

Back under way for the second 45.

Another United sub sees Zac Sapsford replace Kristijan Trapanovski.

Derek McInnes will be the happiest man in Tannadice.

Dundee United started reasonably well, but didn't capitalise.

The first goal was superb and then they get the sending off in their favour. I don't think it should be a sending off - the player hasn't gone in maliciously.

Braga has stepped up in Shankland's absence, wins the penalty and Hearts are 2-0 up and cruising.

In case you needed any indication of Hearts' dominance...

Seven shots to United's one, all of which came inside the box.

As comfortable as you like for the league leaders in that first half.

After a bright start for the hosts, Hearts' opener took the window out their sails and the sending off made things even tougher for Jim Goodwin's side.

It'll be interesting to see how the hosts approach this second half.

Into four minutes of added time at Tannadice.

Pierre Landry Kabore gets onto the end of a lovely pass from Alexandros Kyziridis but the ball gets caught under his feet before he can get a shot away.

Oisin McEntee races in and smashes one goalwards, this one is deflected behind for a corner.

The 3500 strong travelling support certainly in fine voice.

They are absolutely thrilled by what they are seeing at Tannadice - a Hearts side who are utterly dominating.

United simply need the half-time whistle.
