UFC Rules and Regulations

[Knifefighter]

I've got to disagree with KF on that note. If I know one thing, it's how vulnerable our spines our, especially near the back of the neck. A shot to the neck can be fatal, especially with something as powerful as an elbow strike coming straight down. Even if it's not fatal, it can cause major damage which will immediately affect both one's mobility and motor functions.....as well as one's concious faculty:

What leads you to the conclusion that these types of blows can be fatal? How many deaths have you seen from this?

Strikes to the spine and back of the neck are a major tactic of BJJ and have been legal in vale tudo matches in Brazil for over 50 years. Not only have there been zero deaths from this, but there have been no serious injuries.

I've seen Renzo land massive elbow blows on the back of the neck and head to opponents many times without knocking them out, which is why it was very strange that he was "KO'ed" by those two knees from Shamrock.
