Did the Vegas Golden Knights try and pull a fast one at the deadline with Evgenii Dadonov?
The NHL Trade Deadline had already expired when news broke that the Vegas Golden Knights unloaded Evgenii Dadonov to the Anaheim Ducks. There was even some noise that the deal did not make it into the league’s central registry before the 3 PM ET cutoff to submit trades.
That wasn’t the only problem.
Apparently, Vegas’ attempt to unload the 33 year-old’s $5M cap hit in order to make way for Mark Stone’s inevitable return from LTIR hit a snide. Dadonov has a no-move clause and the Ducks were on his list.
Reports suggested that Vegas was not aware of the clause when he was acquired from Ottawa. There was also talking about paper filing being an issue. That’s why it was not considered when Dadonov was moved on Monday.
The NHLPA is now involved disputing the trade.
Golden Knights trade challenged

The situation is still fluid and being looked at with some rumblings that the deal should be rescinded.
Elliotte Friedman broke down the situation in a series of key tweets as follows:
So the questions are: is there documentation and was it disclosed Dadonov was traded to Vegas on July 28. The claim is the paperwork was filed before that. So the questions are: is there documentation and was it disclosed on the July trade call?
Somehow, on trade call from Ottawa to Vegas (a team Dadonov could not block), Golden Knights and NHL were led to believe protection had expired/not filed properly. But, there is correspondence proving no-trade paperwork filed correctly (and on-time) June 30. Dadonov was traded to Vegas on July 28. The claim is the paperwork was filed before that.
So we will see how this is adjudicated. Feel for Dadonov, who did nothing wrong here and is caught in tough spot.
Per CapFriendly, if the trade goes through and is deemed to have been after the 3 PM ET deadline, Dadonov would be ineligible to play for Anaheim for the rest of the season.
