Daniel Mullen seals victory for the Buddies with a shot curling in from the edge of the penalty box.

Debut goal for the English striker who only joined Killie last night.

Graeme Holmes is felled in the box and Craig Malcolm converts. Surely, it's too late for EK...

Aberdeen finally break the deadlock, and they do it from the penalty spot.

Sam Cosgrove is tripped by Rico Quitongo, and he steps up to send the goalkeeper the wrong way from the spot kick.

The visitors take the lead a third time as Charlie Trafford heads in following a corner.

Partick Thistle: Fox, Saunders, O'Ware, McGinty, Penrice, Robson, Cole, MacKinnon, Bannigan, Miller, Rudden.

Substitutes: Sneddon, Cardle, Jones, Harkins, Slater, Zanatta, Austin.

Celtic: Forster, Frimpong, Jullien, Bitton, Taylor, Brown, Ntcham, McGregor, Rogic, Griffiths, Edouard.

Substitutes: Gordon, Simunovic, Bauer, Hayes, Bolingoli, Arzani, Kilmala.

It's just not Bruce Anderson's day. The 21-year-old Aberdeen striker has had to kick his heels on the bench for much of the season behind Sam Cosgrove, Curtis Main and James Wilson.

However, he's been handed his chance today, and twice he goes close to grabbing the goal he craves.

A powerful shot is parried by Dumbarton goalkeeper Conor Brennan, with Anderson blasting the rebound wide.

Minutes later and Anderson hammers a shot at goal, but again Brennan makes the save.

Stevie May dinks home to put the result beyond doubt.

The home side have been on top but the Bully Wee strike first as Ally Love shoots the visitors in front.

Livingston turn the tie around with two goals in two minutes as Lyndon Dykes nets a terrific strike to leave Raith reeling.

The Premiership side are level as Steven Lawless sends the keeper the wrong way from the spot.

Kevin O'Hara with his second goal of the afternoon as his close-range finish hauls Alloa level again.

Hearts are simply walking through this Airdrie defence now. Steven Naismith beats his marker and taps the ball to his left, beyond the outstretched arms of goalkeeper David Hutton and into the path of Euan Henderson, who taps home his first goal for the club.

Leigh Griffiths starts for Celtic at Firhill, which might just quell the speculation about the striker moving on.

Jozo Simunovic is on the bench for the cup holders, as is the lesser-spotted Australian winger Daniel Arzani.

Aberdeen were held to a draw by Stenhousemuir at this stage of the competition last year. And, with 20 minutes left, Dumbarton could well be about to earn a money spinning replay as the home side continue to huff and puff.

The floodlights at McDiarmid Park seem to have been fixed and the second half is set to finally get under way.

Aberdeen continue to put the pressure on. Ash Taylor meets a corner and it takes a deflection before hitting the post and going behind.

But now Dumbarton are starting to get a sight of the Aberdeen goal. Twice Stefan McCluskey gets space down the left-hand side, but his ball into the box on both occasions isn't good enough.

Killie are killing it as attacking midfielder Greg Kiltie nets a deflected strike in his first appearance since returning from a loan spell at Dunfermline.
