Amir Khan didn't let a vicious knockout punch in the face cramp his style ... he partied like a champ arfter losing his fight to Canelo Alvarez.
Khan was at 1OAK shortly after losing big in the 6th. It was lights out even before he hit the canvas, but he rebounded, saying "Im okay everyone. That's boxing for you. congrats to canelo monster punch, much love to all the fans."
