There's a thread on the UG (mma.tv) with this title - started by the brother of the guy you'll see in the following vid.
I suggest reading the thread...this is really serious stuff.

Here's some of what his brother posted so far:
"My little brother got into it with a guy and was stabbed. He was trying to avoid conflict and did not want to strike the guy in order to stay out of trouble. He almost choked the guy out until he pulled out a pocket knife. To top if off they were both charged with battery!
The cops came to the hospital to get his statement. He had lost a lot of blood and was on pain meds by the time they got there. His statement was "he stabbed me". The other guy told them my bro started the fight. I was told that bc of conflicting stories they were both charged and it will have to be sorted out in court. The head investigator is coming to my brothers place today to get his statement. He didnt sound too happy about the way this was be handled when I spoke to him yesterday. He said my brothers charges may be dropped and the other guys may be increased. Ill keep u guys posted. Thanks for the well wishes."
