These days Duncan Keith fights about as often as Muhammad Ali and it shows but he saw his teammate get laid out with a legal hit and went after Desjardins. Once again the refs blew the call by giving Desjardins a match penalty which was rescinded by the league after the game.
The match penalty to Desjardins was rescinded, ref made the right call on the ice and the league made the right call later. You gotta call what you see and if you were on the ice you would have seen the same thing. At first look it did look like a head shot, on slow-mo you see there is no head contact. Good for Keith to step in for a teammate, normally it would be Mayers stepping in when Keith gets hit. Good to see.
