For the third straight game, Manchester was trailing at the half. And for the third straight week, the Lancers needed a late fourth quarter score to win.
Frank Boyd scored with less than 30 seconds left in the game as Manchester slipped past Cosby 21-14. Boyd scored all three Lancer touchdowns along with 144 yards rushing.
Cosby would lead 14-7 at halftime when Joe Hunt scored on the Hook and Ladder play from Ethan West.
But in the second half, Boyd would take over as he scored two of his three touchdowns.
Manchester will host the second round of the 6A South playoffs against Riverbend next Friday.
