Khabib has never been hurt on the feet due to his highly defensive approach on the feet and the tendency to not taking much chance until he tires out his opponent on the ground. Hence, we have yet to seen his true reaction once he is actually hurt. It is very common for the fighters who rarely get tagged during the fight to panic once they are put in a vulnerable position. Conor, for example, had never been rocked by anyone up until the first Nate fight. When Nate hurt him with the one two, Conor lost his composure and shot for a sloppy takedown, which lead him to his demise. For me, this is very intriguing side of this match as I'm very confident that Conor will eventually land clean punch and depend on how Khabib reacts to this unknown territory, the fight will shift to one way or another very quickly.
