On May 17, 2012 Old Dominion announced it would move to C-USA on July 1, 2013. Four ODU sports which are not sponsored by C-USA have outside affiliations. In 2013, the Wrestling team became an associate of the Mid-American Conference and the field hockey team joined the reconfigured Big East Conference. The women's lacrosse team spent the 2014 season (played in the 2013–14 school year) as an independent before joining the Atlantic Sun Conference. Finally, the women's rowing team joined the Big 12 Conference in 2014–15 after the Big 12 effectively took over C-USA rowing. Most recently, the men's swimming and diving team, which was left without a conference affiliation for two years because C-USA sponsors the sport only for women, joined the Coastal Collegiate Swimming Association, later renamed the Coastal Collegiate Sports Association, effective with the 2015–16 season.
