Oilers coach Kris Knoblauch said Wednesday that forward Zach Hyman requires surgery following the upper-body injury that knocked him out of Edmonton’s Game 4 win over the Dallas Stars in the Western Conference finals. He is not expected to be able to play for the remainder of the postseason.

Edmonton Oilers winger Zach Hyman, checked by the Dallas Stars' Mason Marchment on Tuesday, will have surgery and is expected out for the playoffs.

“He’s a top player for us,” defenseman Brett Kulak said. “Tough to lose anybody, but especially he brings an element to the game and to our team that not too many guys around the league can bring to their team. It was tough to see him leave. Hopefully, he’s all right.”
