And besides, I can only speculate that they have seen the weight issue already and did try to compensate and losing those extra baggage by doing lots of drills resulting to another factor that affected his performance.
Trying to lose weight hours before a fight is really an agonizing task and that might result in hurting yourself that is why I'm inclined to believe that the weight issue was the biggest factor why he loses the first fight aside from the fact that Martinez was a replacement fighter.
Just take a look at how Shakur handled that weight issue, he never minds losing the belt rather than hurting himself to shed those excess pounds during the weigh-in, might be a good idea because he performed really well but we can only speculate that if he decided to make the weight he might have lost the fight.
