It's hard to say how long he'll be out but he's 100 per cent doubtful for the weekend, that's for sure.
Notes from Wikiquote
There's no doubt that he's definitely doubtful - I think.
I'm not saying alarm bells are ringing at this moment in time.
If one or two do go out, hopefully the players we get in will be better players.
If that's foreign strength or that's English strength, it doesn't matter to me.
They know, in that changing room, that the strength is that changing room.
