In order for there to be libel, there has to be proveable damages. Plushenko would have to prove that he suffered monetary losses as a result of the libel - like skating shows stopped hiring him, or someone pulled out of negotiations with him because of the slander. If he can't prove losses, then I don't see how he can win the case. But then I don't work in Russia either.
You hope you do realize that you are making no sense. On the one hand you say you don't know how things work in Russia. On the other- you claim what have to be proven. There's no logic in it. What do monetary losses have anything to do with non-material values like dignity and honour? Is it like these things are treated in Canada? Oh...

Material damage and moral damage are two separate claims under the Civil code of Russia. Material is about what you said- monetary losses. i.e. property rights. Moral damage is the physical or moral sufferings, paid when the citizen has been inflicted the said damage by the actions, violating his personal non-property rights, like life, health, personal dignity, the honour and good name. The sums are usually quite symbolic, considering that Brian for example got 17,000 euros from some Miss France who said that he was gay or somesuch, as the reason why their relationships didn't work. Plu with Yana once sued in the civil court the Russian tabloid "Paparazzi" (you can't file criminal charges against not an individual), that wrote that Plu&Yana wedding in the lavender dress was a PR stunt while the legal marriage in fact never happened. Of course they won, the paper aplogized and paid 70,000 RUB to the couple as moral damage. About $2,303? What a hell of money! Surely not enough to pay for all fs tickets a year in Japan that some GS persona normally attends. So, please- no money talk. Because it's just silly.
So is that the end of the matter, then?
T. Akimtseva, a Plu's lawyer, said to mk.ru that they are not going to appeal in the criminal court against this police resolution as invalid (in Russia court has the power to cancel the refusal in the institution of a criminal case if the procedure was violated). She said they got the papers from police where the mentioned linguistic examination concluded that there is basically one phrase that can counts as slander, which police considered as not enough to start criminal investigation. They offered to apply to the civil court, the thing that Plu team are going to do, T. Akimtseva said. She also said Zhenya is overseas having a rehabilitation course now, leaving all the stuff, as I assume, up to his lawyer. Yana is away on holiday with kids and she told Akimtseva that they don't care how exactly Zhurankov will be punished, just that the justice must be done.
What I don't get in the whole story is why Putin returned the article "Slander" in the Criminal code? It wasn't a crime in Medvedev's Russia, now it's back here again. Civil case- for spreading the information discrediting the honour, dignity and business reputation of the citizen. Criminal case- the spreading deliberately falsified information that denigrates the honour and dignity of another person. So, the key difference is "deliberately falsifed", i.e. smth. that Zhurankov knew he can't prove as a true fact. Unless he goes playing an idiot who doesn't watch TV, read Internet, etc., then I don't see why the aricle "Slander" wasn't in apply.
It won't be the first civil case against a sport commentator. Guberniev lost the case in the civil court and paid 75,000 RUB to a goalkeeper (about $2,400, for those who likes counting other people's money). He called the guy a "sh-word" in gates in online broadcast on sportbox.ru, thinking that there was the same commercial break as in TV channel "Rossiya" and believing that the conversation was private, or so he claims. The second example is when the fooball club CSKA sued Sovsport in the court of arbitration (special court, when citizens are not invloved) for their commentator's Utkin comment that the match between CSKA and "Rostov" was match-fixing. CSKA won but refused to accept any compensation of moral damage saying that they do not wish to make money on some utkins. Sovsport had to pay only 2,000 RUB ($65) as court tax. Utkin said that while he respects that court ruling, the "dame-judge", as he put it, doesn't know he specifics of the sport world.
As for Zhurankov, here he is:

In short- he said he didn't claim that Plu's operation was a fake, he only supposed that. He has nothing to apologized for. On the contrary, he made Zhenya some favour that he attracted some attention to his off-ice life and by this Zhurankov sees himself as a community speaker. He also expressed his huge gratitude for the support to the foum FSOnline that he said he hadn't beed reading for 6 years. He also mentioned that Yana's Russian language is under-educated. He pointed out that the X-ray doesn't prove anything because it's not written there whom it belongs to, etc.
