Obviously don't know the full facts so not really much to say except I hope the lad pulls through and my thoughts are with his family.
As for the knobs amongst the Rovers fans - incidents of fighting, threats and breaking seats etc have become progressively worse over the last 12 months, it's very unpleasant and obviously something needs to be done somehow. I love the songs and standing up (at the back) but I must say those that take it too far really do spoil the experience for me sometimes.
