At the end of the night, after the staff broke down the Octagon at UFC 155, former heavyweight champion Junior dos Santos was left without his title and a lumped up face. After the fight, dos Santos gave all the credit to Cain Velasquez for being the better fighter on December 29. Though he still maintains that Velasquez was the better fighter, Dos Santos recently said he had some personal issues going on in his life that affected his performance, plus his doctors told him he could have overtrained for the fight.
Dos Santos told a Brazilian website (Translated by Mixedmartialarts.com):
Really was my head. I had some personal things going on, a bit of my attention was lacking because of it. And another thing. Soon after the fight I went to the hospital and had a scan, which showed my creatine was too high. The normal level is up to 300, mine was in 1400. I also had trouble in the urine and kidneys.
The explanation of the doctors is that I pushed over the line, I over trained, and problems could have happened even before the fight… I was so good that I ended up crossing the line. That was the explanation of doctors. Mine is that I was not good with my head, was having personal problems and did not go well mentally in the fight.
