UPDATE: Alex Kovalev will, in fact, play tonight against the Penguins, and leave for Russia after the game. Sorry for the confusion.
According to TSN's Bob McKenzie, Alex Kovalev is flying out to Russia immediately because his mother-in-law has passed away. He will miss at least two games, including tonight against the Pittsburgh Penguins. Ryan Shannon will play in his absence.
Our condolences to Alex and his family during this time.
