BOULDER, Colo. (AP) — Colorado is leaving the Pac-12, and the Big 12 is ready to welcome the Buffaloes back to the conference they left a dozen years ago.

Colorado’s board of regents voted 9-0 in a special remote meeting Thursday to approve the conference switch in 2024.

“The landscape of collegiate sports is ever-evolving, and the University of Colorado Boulder has determined the Big 12 is the best future fit for our athletic teams,” school President Todd Saliman said.

“After careful thought and consideration, it was determined that a switch in conference would give CU Boulder the stability, resources, and exposure necessary for long-term future success in a college athletics environment that is constantly evolving,” CU Chancellor Philip DiStefano said in a joint statement with Athletic Director Rick George.

“The Big 12’s national reach across three time zones as well as our shared creative vision for the future we feel makes it an excellent fit for CU Boulder, our students, faculty, and alumni,” DiStefano said, adding, “These decisions are never easy and we’ve valued our 12 years as proud members of the Pac-12 Conference. We look forward to achieving new goals while embarking on this exciting next era as members of the Big 12 Conference."

While some of the regents expressed disappointment about leaving the Pac-12, they said the shifting sports landscape left CU no option but to rejoin the conference where they were a founding member in 1996.

The Buffs actually joined the Big Six conference in 1947 and remained with the expanded league for 63 years as it eventually grew into the Big 12.

Colorado will join the Big 12 in 2024 and becomes the third school to leave the Pac-12 in the last year, joining UCLA and USC, which are joining the Big Ten next year.

Big 12 presidents and chancellors voted unanimously Wednesday night to accept Colorado as a new member, clearing the way for the school to leave the Pac-12 and rejoin its former league, a person with knowledge of the meeting told The Associated Press on condition of anonymity because the Big 12 was not making its expansion plans public. ESPN first reported the vote.

Colorado still needs to go through a formal process on its campus in Boulder and officially accept membership.

Pac-12 presidents and chancellors, athletic directors and Commissioner George Kliavkoff were scheduled to convene Thursday to discuss the next moves for the conference, two people with knowledge of the meeting told AP on condition of anonymity because the conference is not making its internal moves public.

Big 12 Commissioner Brett Yormark has spoken for months about his desire to expand the conference and add schools in the Mountain and Pacific time zones. A second person familiar with the Big 12’s expansion aspirations, also speaking on condition of anonymity, told AP the school and league have been in contact for more than a month about a potential departure from the Pac-12.

Colorado’s departure could lead to more defections from the Pac-12, which has seemed vulnerable to more poaching after losing USC and UCLA to the Big Ten and with negotiations for a new media rights contract dragging on. Current deals with ESPN and Fox expire after this school year.

The Los Angeles schools are in their last go-round as Pac-12 members this year. With contractual agreements running out, the Buffaloes are positioned to rejoin the Big 12; the league last year came to an agreement with ESPN and Fox on a six-year extension worth more than $2 billion that runs through 2030-31.

Pac-12 Commissioner George Kliavkoff had said at football media days last week that the 10 remaining conference members were committed to staying together. Text messages to Kliavkoff and Colorado athletic director Rick George were not returned.

Colorado was an original member of the Big 12 in 1996, and joined the Pac-12 in 2011, the same year Nebraska left the Big 12 for the Big Ten. The Buffaloes’ football team has had only one winning record over a full season since joining the Pac-12, and went 1-11 last year, leading to the hiring of former NFL star Deion Sanders.

The Big 12 has 14 members this year, but Texas and Oklahoma are leaving for the Southeastern Conference next year. The second person familiar with the Big 12’s discussions said the conference would ideally like to expand to 16 schools with Arizona, Arizona State, Utah and Colorado all coming over from the Pac-12 to create a Western wing of the league.

Big 12 leadership has also discussed the possibility of trying to add UConn, which won the men’s NCAA basketball tournament earlier this year, and Gonzaga, a basketball powerhouse that does not have a football team, the person said. The Big 12 has been the strongest men’s basketball conference in the country over the last few seasons, and Yormark has said he believes the sport could be a source of untapped value in future media rights deals.

Although the Big 12 landscape is different than it was when Colorado was last a member, the Buffaloes have several rivalries to renew.

“Iowa State is thrilled to welcome the University of Colorado back into the Big 12 Conference,” Iowa State Athletic Director Jamie Pollard said. “The Cyclones and Buffaloes enjoyed a spirited rivalry for more than 60 years in the Big 7, Big 8 and early years of the Big 12, so we are excited to resume competing with them next year.

“This great news for the Big 12 Conference would not have been possible without Commissioner Yormark’s vision as well as the hard work by former Commissioner (Bob) Bowlsby in bringing BYU, UCF, Cincinnati and Houston on board as members in 2023-24. The Big 12 brand has never been stronger, and I believe great days are ahead for our conference.”

Colorado will host former Big 12 conference foe Nebraska Sept. 9.

Big 12 not quite the same, but it feels like home to a 98-year-old Colorado fan

Peggy Coppom hasn't quite seen it all with the Colorado Buffaloes, but she's seen much more than most, so believe her when she says Thursday was a good day to be a fan.

The 98-year-old has been attending football games since her family moved from the high plains of eastern Colorado to Boulder in 1939 to escape the Dust Bowl, and she's missed only a couple home games since buying season tickets in 1966.

The excitement in her voice was obvious during a phone call minutes after university regents approved the school’s return to the Big 12 in 2024.

“I'm so happy to get back to the Big 12 — or the Big 15 or whatever it ends up being," she said, laughing. “It seems like that’s where we belong. We don’t belong with the West Coast people."

Of course, the Big 12 isn't the same league it was when the Buffs left for the Pac-12 in 2012. Nebraska and Missouri are gone, and Oklahoma and Texas will be, too. BYU could become a rival, but the Buffs have little in common with Cincinnati, Houston and Central Florida.

“I wish some of those old schools were there, but we'll make the best of it,” Coppom said.

The conference change, plus the hiring of Deion Sanders, has her eagerly anticipating watching the Buffs from her seats near the 40-yard line on the west side of Folsom Field — “God willing, I always have to add," she said.

Coppom, carrying a gold pom-pom, was escorted onto the field by Sanders during the spring game in April. Coppom said Sanders and the return to the Big 12 has created the most buzz about the team since it won a share of the national championship in 1990.

Former CU fullback Jim Kelleher, who was second in the Big Eight with 15 rushing touchdowns in 1976, said he's in wait-and-see mode about the move.

“I originally wasn’t that excited about it, but at the same time, the Pac-12 had let things get to such a point where you had to do something," he said. "The Big 12 signed a good media rights agreement. It's just sad the Pac-12 hasn't been able to get a TV contract."

Kelleher said that while Colorado will get exposure across three time zones, which is a positive, he's sad to see how traditions and geographic rivalries have been sacrificed with realignment in general.

Specific to Colorado, he said, the Buffs seemed to be a good fit in the Pac-12. He said his sentimental attachment to the Big 12 won't be there without Nebraska and other teams he played against in the old Big Eight.

“Whether it's the school or the individual athletes — with TV and NIL — it's all money, money, money,” he said. “I understand their decision. Hey, I'm part of the Colorado team, so I'm for my team and hope it works out.”

Tom Osborne, the College Football Hall of Fame coach at Nebraska and its former athletic director, shepherded the Cornhuskers’ move from the Big 12 to Big Ten in 2011. He said he's able to view past, present and future realignment from the perspective of both a fan and administrator.

“You're talking about lost traditions,” Osborne said. “I can share the feelings of the fans in that I miss those drives to Manhattan, Kansas; Lawrence, Kansas; Ames, Iowa, and some of those relationships."

Nebraska's move to the Big Ten had as much or more to do with finding stability as it did with finances, Osborne said. In the summer of 2011, Osborne said, Big 12 South teams were negotiating with the Pac-12, Missouri wanted to go to the SEC and Texas A&M also was looking to leave.

“Finances are driving this thing more than anything, and my guess is that the uncertainty about where the Pac-12 stands right now appears to make the Big 12 better for Colorado — even though the Big 12 has not been a paragon of stability.”

Beleaguered Pac-12 says it will pursue expansion with Colorado, USC and UCLA all leaving next year

The Pac-12 Conference issued a statement aimed at stability after Colorado became the third school in a year to announce plans to leave. The nine schools remaining for the 2024-25 season were largely silent Friday.

Colorado on Thursday announced it would join the Big 12 beginning in 2024, joining Big Ten-bound Southern California and UCLA in an exodus that could continue in coming weeks and months. Their departures coincide with the expiration of the league's current media rights deals and the Pac-12 has not yet announced a lucrative deal going forward.

Shortly after CU's regents approved the move to the Big 12, the Pac-12 issued a statement pledging to soldier on. Possible Pac-12 expansion targets could include San Diego State and SMU.

“We are focused on concluding our media rights deal and securing our continued success and growth,” the Pac-12 said. “Immediately following the conclusion of our media rights deal, we will embrace expansion opportunities and bring new fans, markets, excitement and value to the Pac-12.”

The Pac-12's media rights contract expires at the end of the 2023-24 academic year, and Commissioner George Kliavkoff has not noted any progress in landing a new deal.

Oregon State was the only Pac-12 school to comment following the Colorado announcement. A founding member of the league in 1915, Oregon State is considered one of the least likely schools to be poached by another conference.

“Oregon State Athletics trusts that the Pac-12 will secure a media rights deal that will strongly benefit the institutions that are remaining loyal to this conference," Oregon State athletic director Scott Barnes said. "All of us at Oregon State will continue to work hard and diligently to continue the long-term membership and success of our athletic department at a national level.”

Oregon State President Jayathi Murthy said her school joins other members in reaffirming its commitment to the Pac-12.

“We are united by our shared values, our passion for the highest level of intercollegiate athletic competition, our leadership roles as Tier 1 research universities and our support for student-athletes’ academic and athletic excellence,” Murthy said.

The administrations and athletic departments at Utah and Washington declined comment. Arizona State, California and Washington State athletic departments also declined comment, as did the Arizona and Oregon president's offices.

Stanford did not immediately respond to a request for comment.

Arizona, Arizona State and Utah are believed to be potential targets for further Big 12 expansion, though those schools publicly committed to the Pac-12 prior to Colorado’s announced departure. The Big 12 has a six-year, $2 billion contract that is projected to net annual revenue of $31 million for each school.

Under then-Commissioner Kevin Warren, the Big Ten still had eyes out west even after landing USC and UCLA, with Oregon and Washington having the most appeal of the remaining Pac-12 schools. But Warren is gone now and his replacement, Tony Pettit, said earlier this week that the Big Ten isn’t eager to expand more.
