Badminton Brawl at the Canadian Open

I've never been to a professional badminton match but I'm going to guess that this isn't normal. It's not like hockey where the occasional dust up is expected. A week or so ago the Badminton Canadian Open made news after two opponents threw down in a one-sided ass kicking. Two former teammates from the Thailand National team squared off against each other for the first time since their volitile break-up a year ago. Bad blood between the two still runs deep and boiled over at the end of the match with a lopsided beat down. I just might have to start watching more badminton......
