Everyone keeps saying this is a legit loss but it was a headbutt that caused the stoppage and last time I checked headbutts werent legal so I dont count this as a loss rather an unfortunate circumstance. Had it been the other way round and Khan couldnt see I think it would have been a different fight

Anyone who disagrees, try boxing with your eyes closed and then try boxing with your eyes open . You wil see that the luxury of vision makes a world of difference to your performance.
