State of the Skate points me towards this CTV article about Aliona Savchenko (of world champion German pairs skaters Savchenko and Szolkowy) having mononucleosis. It sounds like the pair will not compete at the European championships.
What terrible timing. There is still over a month until the pairs competition at the Olympics but mono really must take a lot out of a person, so I'm unsure if the pair will be able to fully recover. It's so unfortunate, because this pair are Olympic gold medal contenders.
