Hockey is a fast game.

After receiving a breakout pass from Nicklas Backstrom in transition, Nazem Kadri came flying in and clipped Alex Ovechkin with a hip check to the knee, sending the Great Eight spiraling into the air.

Ovechkin left the game favoring his left knee and didn't return for the final two-and-a-half minutes in the first period, but has since returned for the second period. Kadri received a two-minute minor for tripping on the play.

The hip check is a lost art in today's game, begging the question: Was Kadri's hit clean or dirty?
