from Steve Greenberg of the Chicago Sun-Times,

Duncan Keith had enough. Of the Blackhawks getting embarrassed by yet another opponent, probably. Of the Predators’ Miikka Salomaki, definitely.

With the Hawks down 3-0 early in merely the latest first period gone horribly wrong, Keith came unglued. First, he answered a heavy hit from Salomaki by tackling the winger behind the play and punching him. After Alex DeBrincat and Predators defenseman Matt Irwin had a row, Keith seemed to snap, rushing Salomaki again, taking him down to the ice, putting him in a headlock and flipping him onto his back.

For his troubles, Keith was shown the door to the dressing room — his night finished, and his teammates left to try to kill seven minutes of penalties on his lengthy tab. In all, Keith received two minutes for roughing, two for instigating, five for fighting and 10 for misconduct, plus a 10-minute game misconduct. His 29 penalty minutes were the most by a Hawk since David Koci had 30 in 2007.
