ISRAEL ADESANYA , this is his first fight in the UFC and he is a Nigerian born-New Zealand, but he an extensive resume as a kickboxer and boxer. He has only been KO once in 40 fights, he has the cardio to go 12 rounds, so he is not going to gas.
Rob Wilkinson is 6'2 and that might have helped him in the lower levels, but ADESANYA is 6 3' and is going to be the bigger fighter, Something i don't think Wilkinson has seen before.
