It's certainly an extremely likely possibility, at around 50% because it's at USU and it is a rivalry game (at least for them).
The good news for BYU is that USU absolutely sucks. The real question is who is the suckiest right now? I'd think some dignity and pride will kick in and BYU will pull it out, but it will be an ugly game with injuries and cheap penalties.
If we do lose to USU, with just how bad they are this year, then we will definitely be enterring an inner ring of Hades.
