The update says the winner of each first-round pairing will host the region final, making the opening matches especially important.
In Class A, Oneida travel to University School-Johnson City, while Cosby visit Eagleton. The Oneida fixture winner is scheduled to travel to the winner of the Cosby-Eagleton tie.
The other Class A section sees Sequatchie County away to CSLA, with McMinn Central visiting CSAS. Those winners are due to meet for the Region 2 title.
Class AA provides the deepest spread of regional contests. Volunteer are listed away to Elizabethton, while Sullivan East travel to Greeneville in Region 1.
Region 2 features Gibbs at Seymour and Carter at Anderson County. In Region 3, Kingston have home advantage against Soddy Daisy, while Alcoa visit Signal Mountain.
The format leaves little room for a slow start. A single result on 20 October determines not only who advances, but also where the final will be played.
The reported Class AAA schedule includes Sevier County at Science Hill, with Tennessee travelling to Powell in one bracket. Knoxville West and Knoxville Central are also listed on the road, against Powell and Bearden respectively.
The next fixture is therefore the immediate storyline. By the evening of 20 October, the region-final matchups should be known; two days later, the winners will have secured the next step in the state tournament path.
