Edmonton Oilers forward Zach Hyman injured, exits Game 4 - ESPN

EDMONTON, Alberta — Edmonton Oilers' top-line forward Zach Hyman was ruled out for the remainder of Game 4 of the Western Conference Final against the Dallas Stars after taking a hit from forward Mason Marchment, ESPN's Emily Kaplan reported on the game broadcast.

The first-period collision appeared to immediately rattle Hyman, who dropped his stick and appeared to favor his right arm or wrist. Hyman went directly to the Oilers' room and did not return.

Hyman has been a key piece of the Oilers' postseason success, registering a league-leading 119 hits in 14 playoff games while collecting five goals and 11 points. He's a fixture on the team's top forward unit with Connor McDavid and is part of both the Oilers' power play and penalty kill.

Edmonton was already down a forward going into Game 4 with Connor Brown sidelined following a hit from Dallas defenseman Alexander Petrovic in Sunday's Game 3. Victor Arvidsson returned to the lineup as Brown's replacement on the fourth line.
