instead of Portland State @ Oregon State. There were also rumors (before this Portland State rumor) that BYU is trying to move the '25 SUU game.
So, reading between the lines, I believe BYU is hosting Oregon State in '25 and that we are playing Portland State instead of SUU for scheduling timing purposes.
BYU needs a P4 opponent AT HOME. It's not unreasonable to forecast that the Big 12 would approve of a waiver for Oregon State @ BYU to satisfy the P4 scheduling requirement. To support this thought, I note that both Texas Tech and Houston play Oregon State in '25 and that is the only game on either of their OOC schedules that would potentially qualify as a P4 game.
