(I guess some of you might have already figured out who was the person interviewing Brian last night...) Here is the timeline (Japan Standard Time):
2/11 afternoon: group interview after Nam's practice, Brian said Yuzuru is recovering like a machine, doing quads and 3A, will go back to Canada next week. You read this information that night and the next morning.
2/12 at latest before evening: exclusive communication from JSF only to Japanese media (so I didn't receive it and didn't know about it until it was published), saying he injured the ankle and is not practicing, and saying there is some "misunderstanding". You read this information that night and today's morning.
2/12 night after Nam's SP: interview in the mixed zone by me and another Korean journalist (who wrote the article about Brian's perspectives on Sochi Ladies' game published today), Brian talked about "a little ankle issue", and said "hope we can get him to Toronto soon". I regret I didn't check the latest news about his ankle problem before the interview, so I missed this sentence and did not ask further question. You read this information that night from my Weibo and Twitter, but the Korean journalist did not put it in his article (I guess he didn't know about the ankle issue either, because we were not informed by JSF).
2/13 I am really not sure where this "next week back to Toronto" came from. It could be either: another latest communication from JSF exclusive to Japanese media, or another misunderstanding by someone who didn't even know about the previous JSF communication.
