UFC vice president of regulatory affairs Marc Ratner,
“What people are talking about, the night before, there’s a scale where the fighters can come down and check their weight. Some fighters wanted to change the scale from pounds to kilograms, which you can do, and I think that may have knocked it – we don’t have any proof of anything, but it may have knocked the (practice) scale out of calibration. When we found out that there was a problem with the scale early on Friday morning somewhere around 8 or 8:30, we got another scale that was calibrated and put it out there.”
“I am not sure what time that Charles or his camp came down on Friday,” Ratner said. “But he’s saying that he checked the weight on Thursday night, and he was fine. But I can say for sure that Friday there was nothing wrong with the official scale.”
