Cammy Devlin has been ruled out of Hearts' clash with Kilmarnock this weekend after getting his head stitched up while on international duty with Australia.
Devlin took a blow to the head during their friendly defeat to Ecuador and initially played on with a bandage before being replaced on 54 minutes. And Robbie Neilson has confirmed he has been diagnosed with a concussion, and won't be available for their trip to Rugby Park as they look to recover from a recent dip in form and strengthen their grip on third place. Neilson said: "He will miss the game at the weekend. He has concussion. He flagged it up with their doctor. He was delaying his flight home so he won't be home until later tomorrow so he will miss the game."
Hearts travel to Ayrshire just four points ahead of Aberdeen having looked a shoe-in for the position, and accompanying guaranteed European football, just a few weeks ago. Their defeat to the Dons last week was damaging in that regard but Neilson insists any team outside of Celtic and Rangers would want to be in their position.
