The Big Sky, Western Athletic Conference and West Coast Conference are the latest conferences to postpone all fall sports, including football for the Big Sky and WAC, until at least the spring.
WAC commissioner Jeff Hurd said in a statement the conference has suspended "all fall championship and non-championship athletics competition through the end of the calendar year."
The Big Sky announced it intends to play fall sports in the spring.
A statement from the WCC presidents' council, athletic directors and commissioner Gloria Nevarez said the conference will "explore various models" in an attempt to hold fall sports during the spring semester.
The Big Sky presidents' council previously announced plans to delay the start date for its Olympic sports during the fall. That would include soccer, volleyball, cross country, tennis and softball.
A start date for football was going to be "assessed at a later date."
Schools like BYU and San Diego, which play most sports in the WCC, have different affiliations for football because the conference doesn't sponsor the sport. The Cougars play as an independent FBS team, while the Toreros compete in the FCS' Pioneer League.
Per David Cobb, Ben Kercheval and Barrett Sallee of CBS Sports, 11 of 13 FCS conferences had announced no fall sports would be played prior to Thursday's announcement. The FCS football playoffs were also postponed because of the lack of teams playing.
Field hockey, football, men's soccer, women's soccer and women's volleyball are the most common fall sports across the NCAA.
