Dube is one of the players currently awaiting trial for his role in the 2018 team Canada scandal at the World Junior Championship. He is facing one charge in the ordeal but the trial likely will not happen until next year. As such, Dube, along with the rest of the players being charged, are currently in limbo. They seem to be ineligible to play in the NHL and their former teams have all essentially surrendered their rights to them.
However, the KHL is a different beast. It is not uncommon for players with questionable reputations to leave North America for the KHL. As such, it is not particularly surprising to see a player involved in this scandal sign with a team in that league.
Will Dube be the only member of the 2018 bunch to sign in the KHL? Will he even make it to Belarus, or will he be prevented from leaving Canada? All these questions will surely be answered in the coming weeks, so be sure to stay tuned to find out.
