UMass is a member of Division I of the National Collegiate Athletic Association (NCAA). The university is a member of the Atlantic 10 Conference, while playing ice hockey in the Hockey East Association. The football team joined the Mid-American Conference (MAC), in order to play at Football Bowl Subdivision (the sport's highest level) with games played at Gillette Stadium in 2012. In March 2014, the MAC and UMass announced an agreement for the Minutemen football team to leave the conference after the 2015 season due to UMass declining an offer to become a full member of the conference. In the agreement between the MAC and the university, there was a contractual clause that had UMass playing in the MAC as a football-only member for two more seasons if UMass declined a full membership offer. UMass announced that it would look for a "more suitable conference" for the team. UMass Amherst plays most of its home games at the 17,000-seat McGuirk Stadium on campus.
