Since the game will be on CBS and not one of the ESPN/ABC families I doubt they would show up in Oxford.
Unless there is absolutely no other game on their collection.
Ole Miss is not the national name that would cause them to promote another network's offering. Now, an LSU-Florida or Alabama-Tennessee (when both are at the top of their games) or Georgia-Florida or an SECCG like last year all have a national angle and interest. Alabama-Ole Miss, even if both are Top 5, borderline.
My opinion at least.
