Desharnais fought Manson in a heavy hitting, long battle between the two massive defenceman. Manson pulled Desharnais off the boards and literally dragged him into the fight. The two both had moments where they nearly collapsed to the ice, only to get back up and keep going. It's tough to pinpoint where Desharnais could've been injured. A broken hand can be common in a fight, which would sideline him for nearly six weeks - hopefully that's not the case.
Coach Knoblauch mentioned in his post game comments that Desharnais would be evaluated by the medical team right away, so the next time the Oilers practice, we should have an update on his injury and timeline to return.
