GIF: P.K. Subban called for tripping after knee-on-knee collision with Matt D'Agostini

Montreal Canadiens defenseman P.K. Subban found himself in the penalty box after being called for tripping on this rather dangerous looking knee-on-knee collision with Buffalo Sabres forward Matt D'Agostini.

To make matters worse for the Sabres, the Canadiens scored less than a minute after Subban's penalty had expired to give them a 1-0 lead.

D'Agostini did not appear to be injured on the play, but the NHL may take another look due to the somewhat reckless nature of the collision.
