The Winnipeg Jets will be without defenseman Toby Enstrom, who is out indefinitely after sustaining a concussion in a 7-4 loss to the Pittsburgh Penguins on Wednesday. Defenseman Ben Chiarot is a game-time decision because of illness. "Losing a guy like Toby, you can't replace that," defenseman Josh Morrissey said. "For the rest of us, we got to help pick up those minutes, do it by committee." The Jets enter Saturday seven points behind the St. Louis Blues for the second wild card into the Stanley Cup Playoffs from the Western Conference. "For us right now, it's do or die time of the year," Morrissey said. "We can't afford to lose too many games right now. Obviously, we know [Calgary] is coming in hot. We got to be ready right off the start [and] limit our mistakes." Blake Wheeler said it would be a challenge playing the Flames. "They're coming in with a lot of confidence," he said. "They've established their identity with the way they're playing right now. It makes for a tough game, so it's always good to see where you stack up with teams that are playing good hockey." Connor Hellebuyck will make his 13th straight start in goal. He allowed five goals on 15 shots and was pulled in the second period on Wednesday. Winnipeg is 5-10-1 against Pacific Division teams this season.
