Stephen Humphrys should score.

Stephen Kingsley whips a wonderful ball from the left-hand side and Humphrys has a free header - but sticks it straight at Ryan Fulton.

Hearts keep knocking at the door.

82% possession for Hearts. Definitely qualifies as the 'Lion's share'.

Alex Cochrane crosses from the left and finds Jorge Grant, whose shot is blocked.

It's cleared to James Hill whose own effort takes a deflection and spins just wide.

It seems a matter of time.

Best chance of the game.

Robert Snodgrass' corner to the back post drops over Matthew Shiels' head and falls for Stephen Humphrys who clatters a shot inches over.

So far when the ball has been thrown into the box, Hamilton have been able to deal with it pretty well... they're going to have to work their socks off tonight if they want to get anything from this game

Ooft, Hamilton striker Jean-Pierre Tiehi picked up the ball just inside his own half, and only had Toby Sibbick to beat.

He tried to go round him and failed, and then eventually overhit a ball through.

If he'd got past Sibbick he had the whole Hearts half to run into.

Dylan McGowan is trying his hardest to get his side up the pitch when there's a sliver of hope pressure can be eased on the Accies backline.

He's screeching at the top of his lungs to push them up.

That back three has, so far, been a back five almost non-stop.

Accies get through the first 15 mins without conceding.

They've setttled into their defensive shape after a panicked opening few minutes, but they literally can't get a touch of the ball.

Robert Snodgrass whips a wonderful free kick in from the right, which again no maroon jerseys get up to attack.

Hamilton defender Reghan Tumilty goes into the book for a trip.

Hearts playing keep ball.

Hamilton have barely touched the ball in the opening eight minutes.

But crucially, they've defended their box fairly well.

Having said that, Jorge Grant fizzes a ball right across goal which no Hearts player can tap into the net.

Hearts pour forward again.

Stephen Kingsley picks out Jorge Grant in the box but the midfielder's first-time shot is blocked.

A corner comes in from Robert Snodgrass causes havoc before Accies keeper Ryan Fulton eventually dives on the ball.

Hearts are on the front foot immediately. Barrie McKay's shot inside the box is blocked and Stephen Humphrys hooks the follow up wide.

It's like a home game with the amount of Jambos in the ground...

We're under way at the ZLX Stadium (New Douglas Park, for the traditionalists).

What drama awaits?

Hearts have lost three of the last four Scottish Cup finals, twice to Celtic and last year to Rangers.

Midfielder Cammy Devlin says the squad are "desperate to go one better" this time.

It would certainly be a big marker of progress for Hearts if they were to go all the way this time.

Accies captain Dylan McGowan started his career with Hearts alongside his brother Ryan, who won this trophy with the club in 2012.

Now he's spearheading Hamilton's attempts to knock his old club out.

Here's his story.

John Rankin's Hamilton might be bottom of the Championship, but they've gone on an unbeaten run of six matches in league and cup.

They knocked out Premiership side Ross County on penalties in the last round - but this will be an even sterner test for Rankin's young side.

This sounds and feels like a home game for Hearts.

Never before have there been so many away fans at the home of Accies.

The Jambos have the stand behind the goal, the shed beneath the commentary position and half of the main stand... it's a takeover!
