The evidence was clearly visible. Former champion and future hall of famer Rafael Marquez exhibited telltale behavior long before he was put down in the ninth round. Prior to the TKO stoppage, Rafael wandered off to the wrong corner at the end of at least two rounds! He tried to make it look like he did so intentionally. But, as we later found out, his brain wasn’t functioning properly.
Up until that point the fight still appeared close. One judge and Showtime analyst Steve Farhood had the fight a draw. After the stoppage, doctors didn’t like what they were seeing. As a result, they had a stabilizing collar placed around Rafael’s neck, placed him on a gurney and rushed him to the hospital.
The punch that caused Rafael’s problems was a straight right from Efrain Esquivias. It wasn’t a particularly hard punch, but it was timed right and was accurate.
