The visitors lead through Joe Wright's 11th-minute deflected header.

Both sides have had big chances to find the net since, but it remains 1-0 to the Scottish club.

Matty Kennedy tidily cuts inside and manages to force a low cross towards the back post despite having a number of Tromso bodies around him.

Killie skipper Kyle Vassell is at full stretch but can't make contact with the ball to turn it in beyond Jakob Haugaard.

Another good chance for the Kilmarnock striker.

Patient play from Brann before Sander Erik Kartum has a pop.

It's rising from just outside the box, but more brilliant Brann build-up.

The in-direct free-kick is smashed right in to the makeshift Killie wall.

Moments later, Leo Cornic heads wide from another decent Kent-Are Antonsen cross.

In-direct free-kick to Tromso. Robby McCrorie is incensed.

It appears Robby McCrorie tapped the ball down to the ground with his hands before waiting a few seconds and picking the ball up again.

Silly stuff.

A weak header in the middle of the park is capitalised on by Bord Finnhe.

He heads for Ellery Balcombe's goal, and forces the Buddies keeper into a strong save.

But, as expected, the offside flag eventually goes up.

Kyle Vassell skies one from yards out.

Joe Wright knocks on a whipped cross for the Killie captain to meet at the back post, but the striker's outstretched effort somehow doesn't hit the target.

The Killie fans are certainly enjoying themselves in Tromso.

Despite being heavily outnumbered, they're out-signing the home supporters.

Buoyed by seeing their team take an early lead, they're loving life in Norwegian sunshine.

Stunning work on the edge of the box from Brann and it's worked back to Emil Kornvig, who lets fly.

It's still coming down.

Another look at Joe Wright's opener there and there's a good chance it will go down as a Vetle Skjaervik own goal.

Let's hope not. But Killie, and Wright, won't care. They still lead after 30 gone in Tromso.

Jonah Ayunga should have sniffed out where that ball was going.

An absolutely brilliant ball from Shaun Rooney. But again, no gamblers.

Jonah Ayunga, you gotta bust a gut.

Oh Buddies, that was a hold-your-breath moment.

Joachim Soltvedt is right lively again and flashes a ball across the face of goal from inside the box, but there are no takers.

Should he have just taken the shot? Perhaps.

Tromso defender Amadou Barry's header thwacks off Joe Wright's head and falls into the arms of Robby McCrorie.

Danger averted.

Kilmarnock sitting very, very deep here after 28 minutes played.

A sloppy Joe Wright chested back pass gifts Tromso a corner.

Alarm bells ringing for Killie as Tromso come close again.

Kent-Are Antonsen whips in another fine delivery, which once again is knocked toward Robby McCrorie's net.

This time it's Bobby Wales at the far post who is on hand to hook the ball to safety.

A foul throw given, again.

A couple in the Rangers game the other night, too. There are always loads, but rarely pulled up.

In this case, the rain will have played a big part. Clutching at straws here.

Brilliant play from Matty Kennedy. He faces the defender up.

He's maybe not hit the heights this season yet but that's much more like him.

Wanting to take players on. Very positive.

Matty Kennedy jinks inside brilliantly from the left flank and fires at goal.

His shot is deflected behind for a corner, but the ensuing dead ball goes to waste.

They've responded well, St Mirren, but there's not really been that clear-cut shot, except for that very early one for Shaun Rooney.
