Carlos Tevez breaks goalkeeper's jaw with flying knee

Luis Unsain goalkeeper of Newell's receives assistance from his teammates after being hit on his face by Carlos Tevez.

The Old Boys keeper underwent surgery for a double fracture.

Carlos Tevez is not known for timidity. He did break a player's leg last year, after all.

But this latest incident in a Boca Juniors game against Newell's Old Boys is just brutal.

Tevez flew towards goal in search of the ball and collided with Newell's goalkeeper Luis Ezequiel Unsain.
