Springboks vs Scotland in South Africa this year. The Boks launch a counter attack from their own 22, the ball gets to De Villiers as he gets totally blindsided by the big Scottish winger Sean Lamont.
Lamont bounces off him, then De Villiers tosses the ball to a mate and falls over in pain. Huge collision.
De Villiers suffered a pretty bad rib injury from this. Lamont was fine.
