====Affiliate members join====
On June 3, 2013, the Big Ten announced the sponsorship of men's and women's lacrosse. For any conference to qualify for an automatic bid to the NCAA tournament, at least six member schools must play the sport. In women's lacrosse, the addition of Maryland and Rutgers to the Big Ten brought the conference up to the requisite six participants, joining programs at Michigan, Northwestern, Ohio State and Penn State.<ref name="Lacrosse and JHU">{{cite web|title=Big Ten Announces Institution of Men's and Women's Lacrosse and Addition of Johns Hopkins as Men's Lacrosse Sport Affiliate Member|url=http://www.bigten.org/sports/m-lacros/spec-rel/060313aah.html|work=Big Ten Conference|access-date=June 3, 2013|archive-url=https://web.archive.org/web/20130710234815/http://www.bigten.org/sports/m-lacros/spec-rel/060313aah.html|archive-date=July 10, 2013|url-status=dead}}</ref> In men's lacrosse, Ohio State and Penn State were the only existing participants. Coincident with the addition of Maryland and Rutgers, Michigan agreed to upgrade its successful club team to varsity status, giving the Big Ten five sponsoring schools, one short of the minimum six for an automatic bid. [[Johns Hopkins University]] opted to join the conference as its first affiliate member beginning in 2014. Johns Hopkins had been independent in men's lacrosse for 130 years, claiming 44 national championships.<ref name="JHU-hub">{{cite web|title=Johns Hopkins men's lacrosse team to join Big Ten Conference|url=http://hub.jhu.edu/2013/06/03/johns-hopkins-lacrosse-big-ten|work=Hub |publisher=Johns Hopkins University |access-date=June 3, 2013|date=June 3, 2013}}</ref> As long-time independents joined conferences (for example, Syracuse joining the Atlantic Coast Conference), other schools competing as independents in some cases concluded that the inability to earn an automatic bid to the NCAA tournament was becoming a more serious competitive disadvantage in scheduling and recruiting.

On March 23, 2016, the Big Ten Conference and Notre Dame announced the [[Notre Dame Fighting Irish men's ice hockey|Fighting Irish]] would become a men's ice hockey affiliate beginning with the 2017–18 season.<ref>{{cite news |url=http://www.bigten.org/sports/m-hockey/spec-rel/032316aaa.html |title=Big Ten Announces Addition of Notre Dame Men's Ice Hockey as Sport Affiliate Member Beginning with 2017–18 Season |date=March 23, 2016 |work=Big Ten Conference|access-date=June 12, 2016 |archive-url=https://web.archive.org/web/20160528202809/http://www.bigten.org/sports/m-hockey/spec-rel/032316aaa.html |archive-date=May 28, 2016 |url-status=dead }}</ref> Notre Dame had been a member of [[Hockey East]], and the move would save travel time and renew rivalries with former [[Central Collegiate Hockey Association|CCHA]] and [[Western Collegiate Hockey Association|WCHA]] members.
