Matt Duchene hasn't scored a goal since he returned to the lineup from an oblique injury. He returned early from the ailment so it's reasonable to believe that he could still be dealing with an issue there. "It's frustrating," Matt Duchene said after Tuesday's 3-1 loss to Phoenix. "We've got a lot of guys in slumps right now. It's hard, and we're not getting the bounces, but at the same time you've got to work for them, and we didn't work hard enough for them in the first two periods tonight. We were pretty flat."
