The Eastside Eagles dropped their third game of the season, and their second region game, Friday night on the road, succumbing to Lanier's potent offense 40-10 in Sugar Hill, Ga.
The Longhorns rushing attack, spearheaded by Tario Fuller, grounded the Eagles, as Lanier scored four touchdowns on the ground.
Eastside gave up 13 points in the first half before finally putting points on the scoreboard in the second quarter on a Jake Shelton field goal.
Lanier carried just a 10-point lead into halftime, but the Longhorns outscored Eastside 27-7 in the second half.
The win moved the Longhorns to 2-1 in the region after Lanier dropped its lone game of the season to region rival Monroe Area two weeks ago. The win moved Lanier to 2-0 at home.
The Longhorns opened the scoring in the first quarter, taking a 7-0 lead on a 24-yard touchdown pass from quarterback Canyon Cook to Devin Valentine just under six minutes into the contest. Lanier's Ryan Edwards converted the extra-point, but the Longhorns weren't done scoring.
Lanier added another touchdown three minutes later, returning an Austin Holloway interception 65 yards for a touchdown score.
Down by 13 nearing halftime, Eastside's Shelton put the Eagles on the scoreboard for their only points of the first half, connecting on a 31-yard field goal that sent Eastside into the break down 13-3.
Eastside added a pair of scores in the third quarter, the first on a 30-yard Cook run and the second on a Fuller 3-yard run, pushing the Longhorn's lead to 26-3.
Fuller found the end zone again on a 32-yard rush before Eastside crossed the goal line on a 15-yard Holloway touchdown through the air to Quintrell Mathis.
The Longhorns added a 57-yard rushing touchdown with 3:37 to go in the game for the 40-10 final.
Eastside returns to action next Friday at home against Lumpkin County.
Game time is set for 7:30 p.m. at Sharp Stadium.
