The MAC announced Wednesday that UMass is leaving after the 2015 season. The school joined the conference, which consists of FBS universities in Ohio, Michigan, Indiana and Illinois, in 2011.
There was no immediate word whether the UMass football program will enter another conference. The Minutemen began FBS play in 2012 and have a 2-22 record (2-14 in MAC games) in two seasons.
UMass' departure will leave the MAC with 12 schools. When UMass entered the conference, there were 14 football programs before Temple left in March 2012.
The MAC has no plans to expand, commissioner Jon Steinbrecher said.
All of UMass' other sports programs compete in the Atlantic 10 Conference. The MAC offered full membership to UMass in February but was turned down.
"This is not the outcome we anticipated when UMass was admitted as a football-only member," MAC commissioner Jon Steinbrecher said. "However, circumstances changed regarding our football membership and this is a result of those circumstances. I want to thank University of Massachusetts chancellor, Dr. Kumble Subbaswamy, and director of athletics, John McCutcheon, for their professionalism and understanding in reaching this amicable decision."
The MAC is broken into two divisions. The East consists of Akron, Bowling Green, Buffalo, Kent State, Miami (Ohio) and Ohio. The West includes Ball State, Central Michigan, Eastern Michigan, Northern Illinois, Toledo and Western Michigan.
