Liam Millar comes on for his Kilmarnock debut a day after the 19-year-old striker joined on loan from Liverpool.

Fellow forward Rory McKenzie is also on, with Greg Taylor and Chris Burke heading for the dugout.

Burke has been Killie's top performer, but the 35-year-old winger may have been running out of gas.

Kilmarnock are increasing the pressure and Hearts seem content to sit back and contain them.

Home manager Steve Clarke is preparing a double substitution.

Mikael Ndjoli sends an inviting cross high into the Hearts penalty box.

It rises above goalkeeper Colin Doyle, but there are no takers at the back post.

Hearts captain Christophe Berra earns the wrath of referee Steven McLean and goes in the book for delaying a throw in.

The visitors are playing for time it seems.

Hearts make that change and it is on-loan Manchester United wing-back Demetri Mitchell replacing winger Jake Mulraney.

That would appear to be a more defensive move, but Mitchell's strength is going forward.

The ball is taking a fair old pasting and is gathering a bit more ice high up in the cool atmosphere above Rugby Park.

It's descended again into a scrappy affair and it looks like Hearts are going to make a change as they look to change the flow of the game again.

Referee Steven McLean has a word with Jordan Jones after the Killie winger pushes the ball into the stomach of John Souttar after Hearts are given a free-kick.

Souttar gets a ticking off himself for putting his hand on the official's shoulder!

Hearts are keeping Killie at arms length and the home side are having to try their luck from range.

Chris Burke has been impressive, but the winger this time sends his drive well over.

Arnaud Djoum's clumsy challenge from behind on Alan Power gives the Kilmarnock midfielder the chance to eye up the goal from 20 yards.

His curling drive has plenty of gusto, but goalkeeper Colin Doyle pulls out of his attempt to reach the ball at full stretch as it heads wide.

Michael Smith curls a cross to the back post that finds Christophe Berra.

However, the Hearts centre-half glances his header well wide under pressure from his marker.

Hearts get the second half underway and have made a change at the break.

Olly Lee has come into midfield, with winger Callumn Morrison paying for displeasing manager Craig Levein with his first-half performance.

We expected a tight contest tonight, with both defences having reputations for being stingy.

But they could have done with this at the back after it helped clear the pitch of snow.
