White Knoll held a 7-0 lead after an 18-yard touchdown catch by Bruce Wilkinson, but the Yellow Jackets scored 35 consecutive points to take command.
Long scored from a yard out to tie the score with 4:18 remaining in the first quarter and added a 2-yard plunge early in the second quarter to give Fort Mill the lead for good.
Taylor Hemphill scored the first of his two touchdowns on a 14-yard run to start a 21-point spurt in 2:27 for the Yellow Jackets. A White Knoll interception and fumble led to two Yellow Jackets touchdowns in an 11-second span. After a Brandon Plyler interception, Hemphill caught a 12-yard scoring strike from Wells. The Timberwolves then fumbled the kickoff and on the next play Wells found a wide open Chandler Kryst for a 37-yard touchdown to make it 35-7 at the half.
The teams traded scores in the second half. E'Mond Brown and Maurice Jones had scoring runs for White Knoll while Kryst added a 5-yard TD run before Long capped the scoring with a 20-yard burst.
Fort Mill (1-0) will host Lugoff-Elgin next week. White Knoll (0-1) will travel to Wando on Friday.
