Call me "Hadouken." I'm ââ fierce.
But checking a leg kick is not intending to cause damage, it's intended to reduce damage.
It's not a move you "hit", it's a move you use to avoid damage. It's a move used all the time.
How so? It's a move used all the time to defend against a leg kick, and aside from the incredibly rare moments where it has caused injury, it almost never causes injury. That's what makes it a freak accident.
But it's not. Checking leg kicks have been going on forever. This one happened to result in a broken leg, an incredibly rare occurrence.
Weidman didn't do anything which hasn't been done many times before. He didn't end the fight, the injury ended the fight. It's really that simple.
Checking is meant to lessen damage and cause pain/damage to the kicker.
Muay Thai strikers are taught to land kicks with their shins, they are also taught to block kicks with their shins in the event that if the kick is executed where the foot/instep makes contact, the harder shin bone not only softens the blow but may deal damage to the weaker bones of the foot.
The leg break was a complete accident, but checking kicks are meant to result in lessened damage from that single blow and lessened damage in the long run by way of the attacker no longer wishing to bang shin against shin, which can cause damage.
