I think he skipped only one camp. But apparently he wasn't enthusiastic enough in others he did participate. And he was difficult to everyone and had problems with authority figures again.
Because of problems on his personal life he was in practise out of the National Team since September and the deal was, that in Ruka he had a chance to get back. He blew that up and now he is also officially out of the team. Official word is that If he is ready to do some changes on his attitude he may have a chance to get back by performing well at the B-team later this season. Though it seems that educated guesses at press are that this will not happen and that Niemelä doesn't want him back whatever happens.
Then again a lot depends on how well others do. If they do well, it is more probable that Harri is not taken back but if performances of others are not that good and Harri is jumping well, things may change.
And of course all this is only guesses. It may be that they only want Harri to really take a hard look at himself and change his attitude and really work with his problems or it may be, that they are only bullshitting about the chances to come back (because they really don't have a good enough reason to officially ban him for life, but they really want to do so) and have decided that he will not be given any more opportunities.
Time will tell.
And it is also difficult to say how much there are problems between Harri's personal coach Kykkänen and Niemelä. Niemelä seems to blame Kykkänen at least partly at difficulties he has had with Harri and on the other hand he hadn't told Kykkänen about the problems he had with Harri before they talked yesterday at phone. And Harri had neither told Kykkänen about the problems he had had in the camps and that breaking of the trust was one of the reasons Kykkänen quitted.
Harri himself told to press that he plans to take some time off to think about his future and plans and he will later talk more about all this. With press he has been oddly calm about this thing. Even when he heard about his ban at Ruka from the reporter (this, if truth (and at least Niemelä has not denied it,) I think was major screw up from Niemelä, however difficult someone is, you don't tell them about kicking them out through the press but in person) he wasn't volatile. Only said that no one had told him about that, but if it is so, then it is. And yesterday he had answered phone when Ilta-Sanomat called and was calm and talked to the reporter shortly.
