Early in tonight's game between the Dallas Stars and Colorado Avalanche, Nathan MacKinnon hit Chris Tanev, knocking him out of the game.
At the trade deadline, the Dallas Stars sought a shutdown defenseman to counter high-scoring offenses. They brought in Chris Tanev, who has performed well so far.
However, in game four of their series against the Avalanche, Tanev had to leave early after a big hit from Ross Colton. Tanev didn't return after this hit, possibly as a precaution due to the Stars' large lead.
