Zach Hyman’s season – including his gritty, game-shifting playoff performances for the Edmonton Oilers – is over. Head coach Kris Knoblauch broke the news to media on Wednesday, the morning after his National Hockey League team’s 4-1 victory over the Dallas Stars to go up three games to one in the best-of-seven Western Conference final. Knoblauch said Hyman would have surgery after the winger suffered an upper-body injury halfway through the first period of action at Edmonton’s Rogers Place. “He’s getting surgery today,” Knoblauch said before the Oilers left Edmonton for Dallas, where they and the Stars will play Game 5 of the series on Thursday. “It’ll be a while, so we’re not expecting him back for the playoffs.” Hyman was injured 9:13 into the opening frame when Stars winger Mason Marchment hit him in the right shoulder/arm. Marchment’s skates left the ice on the hit, and he wasn’t playing the puck when he made contact with Hyman. No penalty was called on the play. Hyman sits fifth in Oilers’ scoring with five goals and six assists in 15 games played and is third in team plus-minus at plus-11. The 32-year-old winger leads the NHL in post-season hits by a wide margin with 104, 26 more than second-place Sam Bennett of the Florida Panthers. Crude remarks
