My partner had a night out for his friends 30th Saturday night, before this he played football. He was home around midnight Saturday and when he got in the shower had 4 scratches on one side of his back, and one a little further in but the same side and said 'oh I knew that guy scratched me when he grabbed he was a right wanker' obviously all sorts of alarm bells are ringing. Would you believe it was a football injury?
