Patrick Sharp set up Marian Hossa's tying goal in the final minute of regulation and then scored the game-winner 43 seconds into overtime to lift the Chicago Blackhawks to a 3-2 win over the Montreal Canadiens on Wednesday night.
Jeremy Morin also scored in the Blackhawks' fourth straight win overall, and their first in overtime this season after seven losses.
Sharp scored the winner on a shot from the slot that struck Montreal goalie Peter Budaj, rolled high off his equipment, ticked off the left post and landed in the net.
Hossa had tipped in Sharp's feed from the right corner left to tie the game at 2 with 47.7 seconds left in the third period.
Dale Weise and Francis Bouillon scored for Montreal.
