After the teams finished an explosive first period tied 3-3, the game settled into a defensive battle and turned in Chicago's favor midway through the second period.
Sharks forward Andrew Desjardins crushed Blackhawks forward Jamal Mayers on a clean open-ice hit. However, Desjardins' check was ruled as a "hit to the head," and he received a 5-minute major penalty and game misconduct.
In the ensuing 4-on-4, Patrick Kane scored his fifth goal of the season to give Chicago a 4-3 lead. He would also add an empty-net goal late in the third period to ice the game for the Blackhawks.
Aside from the controversy, the action and intensity between the two rivals was fantastic. Expect more of the same as the teams will meet again two more times in February, on Feb. 15 and Feb. 22.
Here are four takeaways from last night's action at the "Shark Tank."
