Approximately 5 seconds elapsed between initiating the takedown and a knockout with strikes on the ground.
A man is able to continue fighting despite having his ear bitten off, and in fact is dominating the fight when the video ends.
Maiming does not necessarily lead to incapacitation and may not discourage your opponent. It may in fact escalate their aggression and the level of force they consider using.
Strikes thrown once a position of control was established on the ground. Other man was unable to escape and effectively helpless.
A skilled grappler may employ this position effectively depending on the situation. However, standing headlocks are commonly used by those who lack grappling skills. This is often not only ineffective, but dangerous as this video demonstrates.
Another demonstration of the danger posed by hard surfaces. Slamming the head this way can easily prive fatal or life changing.
Falls like this can easily kill or paralyse.
