Oregon and Washington appear on the verge of joining the Big Ten. The programs, both charter members of the Pac-12 dating back to 1915, informed Pac-12 presidents Friday that they plan to accept an invitation from the Big Ten once extended, according to Yahoo Sports. The Big Ten is preparing to make those formal offers later Friday, according to multiple reports with Oregon's Board of Trustees scheduling an emergency meeting at 5:30 p.m. ET to discuss "time sensitive athletic conference issues." Oregon and Washington would be the third and fourth Pac-12 schools joining the Big Ten ahead of the 2024-25 season with USC and UCLA previously announcing their planned departures last summer. The Big Ten would then stand as an 18-team conference, the largest in college football history. - David Cobb, CBS Sports Writer SUBSCRIBE TO OUR CHANNEL: https://www.youtube.com/user/CBSSports WATCH CBS Sports HQ: https://www.cbssports.com/live/ Paramount Plus: https://www.paramountplus.com FOLLOW US ON: Facebook - https://www.facebook.com/CBSSports/ Instagram - https://www.instagram.com/cbssports/ Twitter - https://twitter.com/CBSSports #collegefootball #collegesports #ncaa #oregon #washington
