The Big Ten, Pac-12 and ACC will reportedly officially announce an alliance between the three conferences as early as next week, according to Nicole Auerbach of The Athletic on Friday.
The move comes in response to the SEC adding Oklahoma and Texas to become a 16-team conference.
Adam Rittenberg of ESPN first reported news of the alignment between the conferences, which is to "create stability without schools moving conferences."
The Big 12 has not been part of these discussions.
