Edmonton Oilers forward Zach Hyman says his right wrist got dislocated late in the Western Conference final when he was hit by Dallas' Mason Marchment.

Oilers coach Kris Knoblauch said Hyman will have surgery on Wednesday to repair an upper-body injury and is likely to miss the rest of the playoffs. Knoblauch did not disclose details about the injury or the surgery.

The Oilers say they will miss "emotional leader" Zach Hyman, who won't play in the Stanley Cup Final because of a wrist injury.
