That was a tough test for Hearts, Morton put so much into it.

One opportunity is all they needed. They're through to the semi-finals, and that's all that matters.

Kenenth Vargas' 85th-minute strike secures Hearts' spot in the Scottish Cup semi-finals.

They join Aberdeen, Celtic and Rangers in the hat. The draw will be made very shortly live on the BBC Scotland channel.

It's gut-wrenching for Morton and their fans. They gave it their all tonight against the Premiership side.

Morton have four minutes of additional time to prolong their Scottish Cup journey...

Michael Stewart has just awarded Alan Forrest tonight's player of the match award.

Can't disagree with that if you're going for a Hearts player. He's put in a power of work.

Cappielow has never been so quiet.

Five minutes of the 90 left.

Breathtaking stuff.

I think this is probably the first time in the game where Morton look a little bit leggy.

They have done so well to limit Hearts but the players are just half a yard off.

I think not having the options to bring off the bench is killing them but they are still in the game.

Aidan Denholm, just on, is slipped in by Stephen Kingsley but Ryan Mullen superbly stops him with a neat save.

At what cost, though? He's done receiving treatment.

Cammy Devlin fed Shankland through there. It's proved to be his final act.

Aidan Denholm, who just turned 20, is on for the final 10 minutes or so.

That is the opportunity Hearts have been waiting for this whole second half and they've blown it.

How is this still 0-0?!

Lawrence Shankland is through on goal, but he can't get the ball from beneath his feet to get the shot away.

He does the manage to play in Kenneth Vargas.

A huge opportunity, nearly an open goal, he lifts it too high, though and his effort clips the crossbar and it sails into the sea of travelling fans.

Was that the chance?

Hearts are expected to be in semi-finals and finals.

In the performance up to now, you wouldn't say they deserve it but all they need is one chance.

Steven Naismith is encouraging them to get it into Alan Forrest or Lawrence Shankland's feet.

Because of the occasion they seem to be a little bit nervous to take that risk that's going to get them the goal.

Cammy Devlin just trying to place one beyond Ryan Mullen, but the Morton 'keeper shifts his feet well to get across and catch the effort from the edge of the area.

Hearts are hanging on a little bit here.

They had that one chance from Beni Baningime but apart from that, Ryan Mullen has had very little to do.

While David Dickinson has his pencil out, Kirk Broadfoot makes sure his name is scribbled down.

He's said something to one of the officials in the aftermath of that Lawrence Shankland hurl and has worked his way into the little book.

Lawrence Shankland throws Lewis Strapp to the deck with force and a yellow card is given to the Hearts skipper.

It's right in front of the Cowshed and they are crying for a different colour of card.
