The potential addition of Oklahoma and Texas to the Southeastern Conference could cause some major changes across the college football landscape.

"I haven't read the article, but if you're asking me to kind of comment on college athletics, it's changing," Bjork said, according to CBS Sports. "So what does that look like? I don't know. ... We want to be the only SEC program in the state of Texas. There's a reason Texas A&M left the Big 12: to stand alone to have our own identity."

OSU also had a statement on the matter.

"We have heard unconfirmed reports that OU and UT approached Southeastern Conference officials about joining the SEC. We are gathering information and will monitor closely. If true, we would be gravely disappointed.

In the ever-changing college athletic landscape, we will honor our values and ethics as we consider the next steps. Our commitment to our student-athletes is top of mind, and their best interests will be represented prominently.

Like many others, we will use the next four years to fully assess what the landscape will look like in 2025 and beyond.
