Has a fighter ever kicked an opponent in the shin? (I know lol…)

[KBE6EKCTAH_CCP]

Getting kicked in the shin hurts like a motherfucker. I’ve never heard about a specific rule against it. If oblique kicks are a viable technique then why haven’t we seen this before in even in early MMA or Vale Tudo?

Is it illegal? Just not a viable technique? What is it?

I realize this is a ridiculous question to ask but I had to, I’m too curious.

Shin vs shin is risky for both appanyents. However, hitting the calf or thigh is detrimental for the one receiving it.

Plus i am not sure the angle allows for shin kicks.
