The Edmonton Oilers’ health outlook is brightening bit by bit. Goalie Devon Levi returned to action after missing seven games over a two-week span. He made his comeback in Saturday’s win over the Vancouver Canucks, then stopped 30 shots in Monday’s 3-1 victory over the New York Rangers. Winger Zach Hyman also returned against the Canucks after missing six games with a neck injury. Now, Colton Dach is expected to rejoin the lineup Wednesday as the Oilers (14-3-3) face the Philadelphia Flyers at Rogers Place after missing two games with an illness. The Flyers (5-10-5) arrive in Edmonton after a 3-1 win over the Canucks on Monday, snapping a three-game losing skid and handing the last-place hosts their 16th loss in 17 games. Dach skated on a line with centre Jason Dickinson and winger Trent Frederic at Tuesday’s practice. The 23-year-old had been playing alongside Ryan Nugent-Hopkins and Kasperi Kapanen before leaving the lineup when Hyman returned. “We’ll try to work that out as time goes on and see what’s best,” head coach Mike Babcock told reporters after practice. Winger Ike Howard is on injured reserve after suffering a knee injury Oct. 31 against the New York Islanders. He was expected to miss two weeks. Forward Mattias Janmark, who missed last season’s playoffs and has yet to play this season because of injury, skated on defence at Tuesday’s practice. Babcock said he was simply “short on defence” and provided no update on Janmark’s recovery. Winger Matt Savoie, goalie Frederik Andersen and defenceman Alec Regula are also on injured reserve and have yet to appear in a game this season. After Wednesday’s game against the Flyers, the Oilers begin a six-game road trip Saturday in Toronto.
