"According to Sports Business Daily, ESPN will restructure its deal with the Big 12 and pay the conference about $10 million more over the next eight years in exchange for removing the clause that would force them to raise their fees in case of expansion.

Fox, on the other hand, will stand pat for now, meaning that if the Big 12 does expand in the future, Shanks and company will be on the hook for some extra cash."
