Hmmm... or maybe he isn't, this ruling is rather vague...
"Unowned prospects that have not played in the NHL cannot be added to NHL rosters on Yahoo. If such players are called up in real life, then they can be added in Yahoo as soon as a news source confirms that they have been called up by their parent club."
I don't see anything about going through a waiver period, TCA what's the verdict on these situations, first come first serve, or a waiver process?
