Texas Christian accepted an invitation to join the Big 12 Conference yesterday.

The move could provide some much-needed stability to the Big 12, which lost Nebraska (Big Ten) and Colorado (Pac-12) over the summer and will lose Texas A&M to the Southeastern Conference next year

TCU currently competes in the Mountain West Conference and was set to join the Big East next July. Instead, the Big 12 went public with its interest in TCU last week.

Athletic director Chris Del Conte says TCU will pay an exit fee but declined to confirm it was the $5 million required by the Big East policy.

• The Big East gave the go-ahead for the conference to expand to as many as 12 teams for football, which requires attracting six new members.

Yesterday's move is the Big East's first formal attempt to make up for recent losses.

Syracuse and Pittsburgh started the exodus by leaving for the Atlantic Coast Conference. UConn also is interested in the ACC, and there was speculation Rutgers, too, could leave the Big East.

That left the Big East with six football schools: West Virginia, Louisville, Cincinnati, South Florida, Rutgers and Connecticut.

East Carolina has applied to join the Big East.

• Missouri is exploring a move to the Southeastern Conference in hopes of getting as much as $12 million each year in additional TV and cable revenue, according to a confidential document obtained by The Associated Press.

The document outlines the pros and cons of leaving the Big 12 Conference for the SEC.

Among other things, the report outlines the possible contours of broad conference realignment, and it includes recent upheaval in the ACC and Big East.

Under the heading of "possible future conferences" for the Big 12, it lists BYU, Louisville, TCU, West Virginia and Notre Dame (excluding football) as potential new members that could restore the league to full strength.

The report said Missouri would not suffer a dramatic loss in academic prestige with an SEC move.

As for money, the report makes clear Missouri is hopeful for a much bigger payday in the SEC. The report suggests Missouri could earn $17.16 million in Big 12 TV money in fiscal year 2012, compared with $19.25 million in the SEC.

It also envisions a far bigger "per member share potential" should a larger SEC - with millions of more eyeballs in Texas and the Midwest - renegotiate its top-tier TV rights up to $12 million more per year.

• Coach Mike Stoops has been fired halfway through his eighth season at Arizona.

Athletic director Greg Byrne announced Stoops' firing last night, two days after the Wildcats lost their fifth straight game, 37-27 at previously winless Oregon State.

Dating to last season, Arizona has lost 10 of 11 games. Stoops had a 41-50 record with the Wildcats.
