Not saying his knees didn't buckle or that the jab didn't stun him. But part of the reason why he touched was because he wasn't in the most securest of stances. It can happen to any fighter - including granite-chinned ones (Clottey).
People actually think he was hurt there and that's an indication of his chin? He slipped/was off balance, even Khans chin isn't that fragile to be legit hurt from a jab.
knocked off balance, either way it his chins decent enough and he rarely gets hit even with a jab so chill hes still gonna duppy donaire and them
I've lost balance before and walked into a punch as I was already losing balance. Like others said, it happens.
They were saying the same thing when Dawson was dropped by Eric Harding before he fought Adamek (first round). You'd have a point if Rigo was at a standstill, but he was actually moving in when Cordoba landed his jab. It had nothing to do with his chin.
