Well it's not healed. Not exactly surprising, I'd have thought. It's now "officially" accepted that we won't make the group stages. That being the case I have to say that IMHO taking him at all is lunacy.
There are only three other strikers in the squad atm, one of which is the inexperienced TW32 who really isn't likely to start any games, and another of which is Peter Crouch. The third is Owen and if he survives all of the group games he'll have played more consecutive games than he's probably managed for Newcastle this season.
It's time to give up on Rooney and call in another striker, giving him time to get used to being part of the set up.
