I believe Antonio will win the fight in probably the 3rd round because he just has to make it a waiting game to wait back and let Brendan tire out then strike fast and hard.
I believe it will either end in a TKO or a submissiion.
You know, Antonio Rodrigo Nogueira is the former interim UFC Heavyweight Champion and the former Pride Heavyweight Champion and is one of only four men to hold both the UFC and Pride championship belts at the same time.
I doubt he's going to go down easy so he may just not go down at all!
