After Bowen Byram got aggressive clearing Matt Boldy from the front of the net, Boldy let his temper get the best of him. Boldy immediately challenged Byram and dropped his gloves. Byram had no choice but to drop his own gloves in his defense.
During the fight Boldy landed some very solid shots to Byram's head. In most cases I fully support dropping the gloves, but Byram has an extensive concussion history. So much so that Byram has already been forced to contemplate retirement on multiple occasions.
