It will be Ovechkin's ninth appearance in the tournament. He helped Russia win the gold medal last year and in 2008. He has 26 goals and 18 assists in 55 games.
The news that he'll play for Russia comes Tuesday, a day after Ovechkin's Capitals were eliminated in the first round of the NHL playoffs with a 5-0 loss to the New York Rangers in Game 7 of their best-of-seven series.
After leading the league with 32 goals in the regular season, Ovechkin only scored once in the playoffs.
This team has been a real treat to say you've been the head coach of them. I'm extremely proud of this group ... after the disappointment of (the Game 6 loss) is digested, it's always a lot easier as a coach when your team has emptied its tank, and that team emptied its tank for me for three months.
— Senators coach Dave Cameron after getting eliminated in the first round by the Canadiens
