The NHL-leading Ducks also put defenceman Mark Fistric on injured reserve Monday.
Vatanen has 14 points in 39 games for Anaheim this season, and his six goals are tied for the team lead among defencemen. The Finnish Olympic team selection was sent back to Norfolk on Jan. 21 when Luca Sbisa returned to Anaheim's lineup.
Fistric incurred a lower-body injury in Saturday's loss to Dallas. He has five points in 29 games this season.
I kept refreshing the page on the NHL website after the second round and I was shocked he lasted that long. I'm sure the Coyotes were pretty happy to get him. He's such a good player and he plays big in big games.
