I found this as Chaels own version (looks like my memory was a fiction created by someone)
“Paulo Filho put me in a submission and the ref stopped the fight, and I remember one of the promoters came in afterward and said the camera did not pick up the tap,” Sonnen said. “The message there to me was to deny the tap happened and we do a rematch. In my post-fight speech, I said I didn’t tap and questioned why the referee stopped it. I did tap, but we were getting ready to do a rematch. I had an executive director of [the Nevada athletic commission] want to pull my license for making that claim and making his referee look bad. I was like, ‘You have to be kidding me. There were four different cameras there and an entire room full of people. Of course I tapped.’
And Keith Kizer, NSAC, wasn't happy about it
He also would likely need to answer questions about his pending sentencing on a federal charge of money laundering and his criticism of referee Josh Rosenthal following his fight with Paulo Filho at WEC 31. (Sonnen claimed he didn’t submit to Filho in the second round of the fight.)
“You want to criticize a referee and say, ‘I don’t think he did a very good job,’ that’s one thing,” Kizer said. “But to out and out lie about what happened in the match is a different thing. So I think that will get brought up as well because I’d bring it up.”
