More tough injury news for the Edmonton Oilers — winger Taylor Hall will be out four weeks with a knee injury according to general manager Craig MacTavish. Hall was hurt Saturday versus the Senators in Ottawa. For the 21-year-old it’s just the latest entry in an injury log that’s already fairly long for a player his age. The Oilers (2-6-1) are also still without center Sam Gagner (broken jaw) and veteran winger Ryan Smyth (groin) will apparently be out for a week.
