No denying these injuries are worrying, we've zero cover at centre half if both Wilson's are out for any length of time, also if we're in the position where we're relying on Brown and Croft then we're in deep trouble, they've had hardly any game time apart from anything else.
Also there is no way Murphy will come back, he won't even be asked to, he's been shipped out twice this season already so he's not exactly high up in the pecking order.
