Hyman underwent surgery for the injury Wednesday and will not play when Edmonton tries to close out Dallas in Game 5 at American Airlines Center on Thursday (8 p.m. ET; ESPN+, ESPN, SN, TVAS, CBC), with the Oilers holding a 3-1 lead in the best-of-7 series.

Known as a relentless forechecker, Hyman was on track to break the NHL record for most hits in a single postseason. After being credited with two hits before exiting Tuesday’s game, Hyman was up to 111 – just 15 shy of then-Tampa Bay Lightning winger Blake Coleman’s mark of 126 in 2020.

The Edmonton Oilers come out of Tuesday’s Game 4 win with the prospect of returning to the Stanley Cup final and avenging last year’s loss.

EDMONTON -- Zach Hyman is likely out for the rest of the Stanley Cup Playoffs with an upper-body injury sustained in the Edmonton Oilers' 4-1 win against the Dallas Stars in Game 4 of the Western Conference Final at Rogers Place on Tuesday, coach Kris Knoblauch said. The forward will have surgery Wednesday.

“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.”

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.

It’s clear now the Edmonton Oilers must go with a “next man up” mentality after likely losing Zach Hyman for the rest of the playoffs.
