The Big 12 Conference has added three affiliate members in women’s lacrosse and two in rowing for the 2024-25 academic year, supporting the growth of women’s sports across the Conference. Affiliate members will compete for the Conference’s postseason championship in both sports, with lacrosse members also competing in regular season competition. The league’s first-ever women’s lacrosse season in 2025 will feature a single round-robin format, with the top four teams advancing to the Big 12 Championship.
Oregon State and Washington State are reportedly close to joining the West Coast Conference as affiliate members in multiple sports, particularly men's and women's basketball. This agreement is similar to their arrangement with the Mountain West Conference for football games, but with the expectation that their games will count towards the standings in other sports within the WCC. The deal is still being finalized and comes after a court ruling granted control of the Pac-12 board of directors to OSU and WSU. The schools intend to rebuild the Pac-12 and will continue to display the conference's branding on their football fields, despite operating as a two-team conference.
