This is a vid of the fight highlights. Something happened between the 4th and 5th rounds. Stevenson is clearly mixing up his feet and from here on in, kept moving to one side and being hit with the same punch over and over again- The left and right jab/cross to the right side of his head.

Even though he was throwing punches back, when you see a fighter staggering around on his feet and being hit with the same punch over and over again, you have to realize something is wrong. But hard to notice that when a fight is a fight.

There is nothing the ref could have done here. The fight had to continue. Even though Stevenson was going to burn out and crash sooner than later. I'm surprised he stood up that long, especially after the 8th. Fight could have been stopped at the 8th or 9th round by his CORNER.

I would bet you ANYTHING that Stevenson was slurring, not responsive to any commands by his corner and effectively just being sent out there to fight on air.

Sad, really! The corner was bad here.
