After Mt. Juliet goal keeper Baker Bachman turned away a Commando penalty kick, junior Colbe Earles scored the game-winner for the Bears just as he did last week.
Late in the first half, Joseph Earl scored Hendersonvilles lone regulation goal. Mt. Juliet's Eric Whitmire scored on a penalty kick with 13 minutes left in regulation play to tie the score.
Hendersonville will travel to Franklin for a 6 p.m. sectional against Franklin. Mt. Juliet will play host to Ravenwood Saturday in their sectional meeting.
Franklin defeated Ravenwood 2-0 in Thursday's Region 6 final.
