Josh Thomson re-emerged in the UFC in a big way with a TKO win over Nate Diaz at UFC on Fox 7. It was the first time Diaz had been stopped by strikes in his career, and it rocketed Thomson into the top 10 in the UFC official rankings. A few weeks after the fight, Diaz was a guest on BJPenn.com radio and went off on Thomson, accusing him of running and making "woman noises" throughout their fight. He also demanded a rematch. Thomson responded in his own interview on BJPenn.com radio, and he hurled quite an accusation at Nate - that he never actually made weight for the bout:
"I think the biggest thing is this; he is interested in a rematch with me, one thing he needs to remember before the fight even happened, he was complaining after weigh in's about how he was moving back up to 170, so he couldn't even make weight when we fought the first time. Nate knows this."
"I am going to say this directly to him. Nate, you didn't make the weight, so how are you going to make the weight when we fight again? That's the thing that's discerning, we all let it slide because it was a huge fight, but you didn't make the weight and you still lost. So unless you plan on fighting me a 170 then I'm not really interested. Like I said, I'm looking forward to the title shot, I'm looking forward to getting in there for the title. If I have to go through him again to do it, then so be it. Maybe you should start watching what you eat, maybe you should start doing that to take care of yourself. You couldn't make the weight the first time and that was something I was going to keep to myself, but you want to start talking trash? Saying all these things, knowing that I beat you fair and square, I guess next time we'll take 20% of your purse if you don't make weight."
"It's an issue I could have brought up and made a big deal about but I didn't do it because that's not the kind of person I am. I could have made a big fuss and taken it, rubbed some salt in the wound and taken 20% percent of your purse after you lost, but I didn't That's the kind of person I am, I moved on and I suggest you do the same thing."
At the weigh-ins, Nate did initially weigh in at 157 pounds. You can see in the video (starting at around the 26-minute mark) that after he misses, he takes off his boxers and tries again. As he stands on the scale, there's a discussion between Dana White and a few other men, one of which presumably works for the commission. After some back and forth, they declare that he's 156 and that's that. But there could definitely be something to Thomson's accusation, because it did look kind of fishy.
Regardless, Thomson won the fight and a rematch is highly unlikely. But it does put the spotlight onto how these things go down sometimes. Is it shady? Or is it a whole lot of nothing? It's certainly nothing on the level of the weight "scandal" at UFC 158 with George St. Pierre and Nate's brother Nick Diaz, but it's interesting nonetheless.
