I copped a groin injury during pre season and it stopped me playing for the year. The pain after it cooled down that night and for quite some time after was severe. Even swimming 2/3 months later I needed a float between my legs such was the discomfort if my legs kicked. Like Steven May I had a scan and it showed nothing.
When I saw Joel Smith still running around in the Lions game and it was known he had a groin injury I was yelling at the monitor (I'm in Bangkok) Get him the [censored] off now!
