Avs captain Joe Sakic, already sidelined with a herniated disc, he's now expected to be out for 3 more months due to an accident with a snowblower that occurred at his home.  My guess is that he stuck his hand in the machine.  Even if the motor is off, the blades are still under tension, and once clear of ice and debris, they snap back into place.  He underwent surgery Tuesday night to repair three broken fingers and tendon damage, but he is expected to make a full recovery.
