Justin Tafa made the wrong kind of history at UFC Vegas 45 when he became the first UFC heavyweight to miss weight. He came in at 267 instead of the allowed 265-266 pounds.

The UFC heavyweight explained exactly what went wrong at the latest event. It seems things just didn't go right physically for Justin Tafa.

“For me, man, usually, if I get the same purses every time, then everything works out good,” Tafa told reporters, including MMA Junkie, at the UFC Vegas 45 post-fight news conference. “This week I water-loaded like I usually did, but I lost no weight at all, and I knew by the time it hit Thursday, I was like, ‘Damn, man.’ Usually I’m down four, five pounds. I knew it was gonna be a hard cut. I sauna’d for like 11, 12 hours just to get it and by the time I hit that last pound, I was just like, ‘No, I don’t think I could fight if I continued.’ But you know, the goal of mine was to make history, and that wasn’t the way I wanted to.”

He continued, “I was done, bro. Everyone that was there, the PI could see how much work I put in there, and I was barely making it. It was unprofessional of me, and it will never happen again, and I apologize to all those that were involved, but Harry got that purse. A one-pound disadvantage at heavyweight isn’t the same as a one-pound disadvantage at featherweight. We’re heavyweights at the end of the day, and he still got that 30 percent, but he’s going home with a sore head, and I’m going home with my hands raised.”

Justin Tafa laughed at the end of the presser and said that his New Years' resolution was to ‘make weight.' The UFC heavyweight will be hoping he doesn't get a chance to make history like that ever again.
