Gave the ref a decision to make

I've just watched that period of the match again, because I had a vague recollection of something happening shortly after the red card. The only thing I found down that side was a shoulder barge into the back of Kitching. He stayed down briefly holding his knee. But there wasn't an elbow, and nothing to warrant even a booking from what I've seen. The Barnsley fans booed at that point because a card wasn't shown, but I honestly don't think there was much in it, and nothing remotely like Watters challenge where he's clearly not trying to play the ball.
