EDMONTON, Alberta — Edmonton Oilers’ top-line forward Zach Hyman sat out most of the club’s 4-1 win in Game 4 of the Western Conference finals Tuesday over the Dallas Stars after taking a hit from forward Mason Marchment in the first period.

The first-period collision appeared to rattle Hyman, who dropped his stick and seemed to favor his right arm or wrist. Hyman went directly to the Oilers’ dressing room and did not return, though he was in the locker room with his teammates after the victory.

Edmonton coach Kris Knoblauch told reporters after the game that he would have an update on Hyman on Wednesday.

Hyman has been a key member of the Oilers’ postseason success, registering a league-leading 119 hits in 14 playoff games and scoring 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, which is now up 3-1 in the series, was already down a forward going into Game 4 with Connor Brown sidelined after a hit from Dallas defenseman Alexander Petrovic in Sunday’s Game 3. Viktor Arvidsson returned to the lineup as Brown’s replacement on the fourth line.

Game 5 is Thursday in Dallas.
