I think Lennox Lewis took out Razor Ruddock with a nasty shot to the temple if I'm remembering correctly.
Interesting thing about the forehead. Someone mentioned that JMM moves his forehead into a punch instead of getting hit on the jaw. This explains why most KO are not from punches to the temple.
Hopkins was taking some nasty shots off kovalev onto the temple, some he didnt ride at all. That man has one of the best chins ever.
One of my pet hates in boxing is when a fighter is clearly out cold and the referee stands over him counting right to 10. The guy is clearly in a bad way and frankly these referees should try something else, useless.
