He has emptied his heart and soul in the octagon like nobody else. You know how some guys have had 2-3 maybe 4 wars and then completely fall off? Diego has had like 15 of them. Tonight it was clear that he has nothing left, that's all. No shame in that. Also, he had been getting beat up for the entire fight and the knee that landed was big and caused a cut. I was surprised the ref was asking him so many times. He should've called it off quicker.
