Butler plans to join the Atlantic 10 this fall instead of the original plan to join in 2013, reports CBSSports.com.
Last month, Butler said it was leaving the Horizon League.
Butler and VCU will replace Temple which is joining the Big East as a football member this season and a all-sports member in 2013, and Charlotte who is leaving to join Conference USA. VCU wanted to join this year because their basketball team would not be eligible for the conference tournament. The Atlantic 10 will have 16 league members in 2012 and 14 members next year when Temple and Charlotte depart.
