in Portland. If we end up as a 10 seed then that's possible. 1 possible scenario would have BYU playing San Diego State in the 7/10 matchup with the winner going on to play Arizona in the round of 32 (sounds oddly like the Maui Invitational this year but in Portland instead of Maui).
The committee does try to avoid rematches in the 1st round if possible, so odds aren't great that would happen. However, that's a rule that has flexibility and due to BYU's no-Sunday play policy it's something that can be difficult to avoid at times (just look at last year's rematch vs. Oregon).
