I think the 'rumour' is that he's struggling head wise. One of these whereby the amount of bumps that you've taken over the years catch up with you and you get advised by quacks to knock it on the head (bum bum).
Hopefully this is just as rumours do, escalating. I'm sure he has got currently a problem with his head, it may keep him sidelined for a week or two but lets hope it's all been blown out of proportion.
I'm sure the club will be doing the right things, player welfare and all that. They'll be taking the right steps, getting him looked at etc.
