I just watched that event again and something in the Yves Edwards vs. Joao Marcos Pierini fight caught my attention for the first time.
When Yves landed that SICK high kick and then backed off to get him to stand up, Joao got up and kind of stood behind the ref and said "My shoulders out". The ref then called time out and took him over to see the doctor.
The doctor said "Your shoulders not out, where does it hurt?". Joao replied, "my shoulders out".
Obviously Joao was still reeling from the effects of that kick but was something really wrong with his shoulder or was that just a way out for a defeated man?
I dont know, but here is an idea: Keep in mind, Joao has bad english (in all likelyhood). He may have been numb, unalbe to feel his shoulder. Kicks to the neck will do that to you...
