Per TSSAA website
Division I Tournament Site - All region tournament games will be played at the higher seed. If two schools are the same seed, the district that was scheduled to host the region tournament will be considered the higher seeded team and will host that game (Due to it being an odd-numbered year, the odd-numbered district (1, 3, 5, 7, 9, 11, 13, 15) shall host the game.).
