Risks of MMA fighting?

Concussions happen ALL the time in MMA. In organizations such as UFC, Strikeforce, and Bellator. Severe injurys such as major cuts, broken orbitals, and cracked ribs are also common. As far as "life threatening" injurys... no. Major organizations such as those take lots and lots of medical precautions. No death has ever been reported in Major orgs. But in MMA's history their have been 3 toatal deaths reported. One of those happened in houston after a fighter was knocked out, he simply never woke up. Their was something wrong with his brain which could of been detected if he would've gotten a catscan. Something similar to that happened in northcarolina a few years ago. And most recently in an amateur fight in Iowa, a fighter shot for a take down, got caught in a choke and his head slammed into the canvas causing his one vertebre to get damaged and he is now paralyzed from the neck down. So ofcourse its dangerous, but "severe" injurys are not very common. But this is a combat sport, so its no suprise.
