Dadonov's trade to Anaheim is currently being reviewed by the NHL and NHLPA, leaving his status as a member of the Ducks in flux, Jesse Granger of The Athletic reports.
According to reports, Dadonov's contract contains a modified no-trade clause that requires him to submit a 10-team list of prohibited teams that presumably includes Anaheim. If the trade is indeed voided, the Russian winger would remain on the Golden Knights' roster while John Moore and Ryan Kesler's contract would revert to the Ducks.
