straight away, he fell back like he'd been shot and hit the ground as if he was injured. There's no doubt it hit the back of his hand, I'll leave it to others to say if that was accidental. I can't see how it couldn't be accidental or whether that's inconsequential. I don't think it had anything to do with the clock that VAR called the ref over. They've still got to beat a rampant Hearts and Celtic aren't playing well.
