Texas A&M officials have formally told the Big 12 they are considering leaving the conference and want to know the process if they do.
Texas A&M has expressed interest in joining the Southeastern Conference.
Texas A&M President Bowen Loftin's letter to conference Commissioner Dan Beebe says it should not be considered notice that the Aggies have decided to leave. He says the school faces a decision that will shape its future for the next 100 years.
If Texas A&M leaves the Big 12, the move could create a shake-up across college sports. In 2010, Texas considered offers to join the Big Ten and the Pac 10 before deciding to stay in the Big 12.
Nebraska (Big Ten) and Colorado (Pac-12) left the Big 12 in July.
