Watch a pane of glass wipe out a referee in Pittsburgh (Video)

These days, with all the reckless hitting in the game, there are all sorts of possibilities one has to consider when going into the corner. However, you'd think falling panes of glass wouldn't be one of them, especially in a swanky new arena like the Consol Energy Center.

Unfortunately, as referee Kevin Pollock learned the hard way in the first period of Friday's tilt between the Pittsburgh Penguins and the Montreal Canadiens, sometimes you do.

My favourite moment is when Alexei Emelin and Eric Tangradi, who collided to knock the pane loose, put aside their petty differences to help Pollock up.

As I always say, referees are a lot like pretty ladies: when one gets wiped out by a pane of glass, everyone's a perfect gentleman.
