Late this morning, Nebraska officials contacted the Big Ten office, informing the league of the decision. Nebraska will become the 12th member of the Big Ten.
Meanwhile, University of Texas regents will meet next week to decide whether the Longhorns will remain in the Big 12 or switch to another conference.
Big 12 D-Day is Tuesday.
UPDATE: MSU AD Mark Hollis is tweeting it, so that's basically official. No more "anonymous sources."
UPDATE II: Showing the backbone we associate with true leadership, Hollis has deleted that tweet.
UPDATE III: From the Michigan AD:
Statement from Athletic Director Dave Brandon
I can confirm that Nebraska has applied to the Big Ten Conference for membership. I can also confirm that the Big Ten has done its due diligence as it relates to Nebraska. I expect that an announcement will be forthcoming from the Big Ten in regard to Nebraska’s membership very soon.
Here's a hint as to the outcome: The BTN is going to televise Nebraska's 6PM EST press conference.
