Missouri curators met behind closed doors last night for the fourth time in as many days as the school turns its attention to saving the Big 12 Conference after its apparent bid to join the Big Ten failed.

The meeting follows 2 days of discussions in Columbia amid a shifting landscape that saw fellow Big 12 members Colorado and Nebraska bolt for the Pac-10 and Big Ten, respectively.

Missouri was considered one of the top prospects for an expanded Big Ten, and the school could still wind up there as conference realignment continues to unfold.

For now, school officials are publicly pledging their loyalty to a 10-team Big 12 - even as their counterparts in Texas and Oklahoma prepare for meetings this week that could result in an exodus from the conference, with as many as five Big 12 teams possibly headed to the Pac-10.
