Kudos to both fighters. But Khan deserves all the accolades. The accidental headbutt is always very unfornate especially in the big event like that. But still,.. Khan won that fight CONVINCINGLY. He was too fast, he fought the smart fight, he got tagged by a couple of flush left hooks in the chin, and he took it like nothing. And for that, we should not make any excuses for the great Barrera's defeat.
