I'm guessing the appointment will determine if he's ready to start training again, and whether or not playing at the WTFs is possible.
That seems the most likely thing to me.
Just a thought - who is this Chris Jones anyway? What's his involvement with Andy? Is he part of his Management Team? A close friend (if so I don't think he had any right to divulge this info unless he had Andy's consent)? Maybe a sports journalist? I'm not saying his tweet is necessarily inaccurate, but it would nice to know who the tweeters who make these sort of announcements are.
