Rangers boss Graeme Murty has revealed that he has regrets over substituting Andy Halliday before half time of the Scottish Cup semi-final with Celtic.

Halliday reacted angrily to being hauled off before the break, and Rangers went on to suffer a 4-0 defeat to their fierce rivals at Hampden Park.

Murty has insisted that he made the correct decision, but acknowledged that he had put Halliday in a "horrible" situation as a result of wanting to make a tactical alteration.

The 43-year-old is quoted by The Scotsman as saying: "On a personal level, no-one likes to come off at that time and the impact of that has been hard. I regret that as a human being. But in terms of a professional level I had to make a decision to alter the shape of the game.

"Andy was the unfortunate guy. It's horrible. It happens. It's football. He didn't vent it at me as he came off. I didn't know about it until afterwards. I've no idea who it was aimed at."

After the game, both Lee Wallace and Kenny Miller were involved in a disagreement with Murty and have since been suspended.
