People with knowledge of the decision say Big 12 leaders have agreed to invite TCU to join the fractured league as early as the 2012 football season.
The offer to TCU will be extended sometime in the next few days, according to two people with ties to the Big 12. The people spoke only on condition of anonymity because the league has not announced the decision.
The Big 12 board of directors authorized interim commissioner Chuck Neinas to begin negotiations with TCU to become the Big 12's 10th member, the league announced on Thursday. He'll begin discussions immediately.
The vote was unanimous, but Missouri did not participate on the advice of legal counsel.
