Yeah, it did... Here is a link that mentions it. I thought I had remembered this.

I was thinking about this over the holiday. If were are into conspiracy theories here as Scab mentions, then I think it might be possible that someone from Chizik's camp leaked the investigation in Auburn. He would still get his buyout based on the above - but he could certainly put a chill on their coaching hire going forward with the NCAA snooping around. By doing this its just a little payback for all that went down on the Cam thing.
Based on my interpretation of his whole tenure, Chizik was hired by Dye and the PTBs there to be more or less a figurehead coach. I think his staff was largely put together for him, including Trooper and Luper and maybe even Malzahn. After winning the national championship he renegotiates his contract with a high buyout that gets paid even in the event of a NCAA investigation. How does that happen? I think it suggests that Chizik wanted to get paid for going along with the scams to get Cam and other players and knowing how the machine operated. Just like any good coach is coached to do - dont leave any money on the table on the way out. Auburn paid Tuberville under basically the same circumstances essentially because he was a good man. And just like with Bowden you have not heard a peep from Tuberville about his time there and neither will you hear from Chizik either. Malzahn leaves for a head job but lesser money but knew inevitably that he would be tainted for life if stayed any longer. This entire season and the downfall of the program is being placed a Chiz's feet and this could be the only payback he gets on the way out.
The upper structure of the Athletic Dept has kept this investigation as quiet as possible for the last several months. They had every reason to keep the investigation quiet because they knew it would hurt recruiting and the new hire effort. The AU AD didnt need to disclose this at this particular time to justify firing Chizik - they already had all the public support from their fan base prior to this information. That's why I believe someone from Gene's camp leaked this info out.
