Trailing 2-0 after two periods, the Amerks came on strong in the final frame to make it a game. Kassian got the ball rolling with his eighth of the year on the power play just 15-seconds in. Minutes later, T.J. Brennan potted his seventh goal of the year to knot the game 2-2. The Bears would get the lead back before Kassian's second of the night with 1:01 left in regulation forced the OT.

Brennan: G, +1, 4 SOG
