Dundee United players were left perplexed at Rugby Park on Tuesday evening after a Kilmarnock fan slapped them on the head upon exiting the dugout in their 2-1 Premier Sports Cup loss to the hosts.
Liam Fox's side took to Ayrshire in the hope of presenting their fans with at least a glimmer of trophy cabinet success, knowing that a win against Derek McInnes' men would put them within two games of cup glory via the semi-final.
That didn't go to plan, however. Kyle Lafferty 's early strike from the penalty spot was quickly cancelled out by a Glenn Middleton effort in a pulsating tie - though Dan Armstrong's winner was enough to send Killie through to the knockouts where they await tonight's draw.
And the day started in bizarre fashion for Tangerines players - after footage showed Fox's men being slapped by a Kilmarnock fan as they emerged from the dugout for the first half.
