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.
I don't think today was my most solid game that I've had, some rebounds here and there. I know there's a lot of work to do, not every game is going to go as good as these last few. I've just got to make sure I keep working and keep trying to get better.
