I don't know if he quit, he was getting a good ass kicking. I thought he was done at the end of 4, I didn't think he was getting out of those ropes. At least he fought on and tried to throw some big shots in the 5th. He just has no power at 154 at all. Cintron should retire, or at the very least move down to WW, though his big money fights are a thing of the past.
That shot to the temple or side of the head had a lot to do with it. He was done after that shot and never recovered.
Cintron didn't quit (not this time at least), he just got ass rammed by cinnamon. What the **** happened to Kermit's punching technique though? The dude used to have a great jab, left hook, and right hand and NONE of those have any bit of snap or body to them anymore. He's completely stopped turning through his shots.
