According to a report from ESPN’s Andy Katz, Butler will officially join the Atlantic 10 conference tomorrow for the 2013-14 school year.

Katz reported that Butler will leave the Horizon League in all sports. No mention is made of Butler’s football team, which is a member of the Pioneer Football league, but earlier reports about a possible move indicated the team would remain where it is now.

The Bulldogs will replace Temple in the Atlantic 10 and will now be in the same conference as Xavier, Dayton and 11 other schools.

Reports have also suggested that the Atlantic 10 is in talks with Virginia Commonwealth and George Mason, both memebers of the Colonial Athletic Association.

An official announcement of the jump is expected tomorrow.
