Collinwood held a 14-12 lead early in the second before Cornersville scored two straight touchdowns to take a 24-14 advantage into halftime.
The Trojans then returned an interception for a touchdown early in the third quarter to cut the deficit to 24-20, but the Bulldogs kept Collinwood at bay by reaching the end zone on their next two drives to claim the 12-point win.
"It's kind of a culmination of a lot of hard work. We've come close a few times this season, but came up a little short," said Cornersville coach Ray Stocstill. "This puts us in a position to possibly end the season with two straight wins and help build some momentum for next season."
Despite committing two turnovers, the Bulldogs(1-8, 1-5 District) racked up 407 yards of total offense, which included 234 yards rushing on 30 carries. Tailback Jonathan Douglas spearheaded Cornersville's offensive attack by rushing for a career high 187 yards and two touchdowns on 21 carries to go along with three receptions for 19 yards. Dusty Currington also toted the ball nine times for 47 yards and caught one pass for six yards.
Bulldog quarterback Hayden McMahon complemented Cornersville's ground game by completing 11-of-16 passes for 173 yards and four touchdowns to go along with two interceptions.
Dillon Bean snared three passes for 66 yards and two touchdowns to lead the Bulldogs' receiving corps, while Mikie Adams and Stone Riner each caught two passes for 52 and 30 yards respectively with Adams scoring twice.
Collinwood (1-8, 1-5 District), meanwhile, tallied 229 yards on the ground, but mustered only 37 yards passing en route to finishing with 266 yards of total offense.
Senior linebacker Jessie Gower paced Cornersville's defense with 11 tackles, while defensive end Jacob Gentry and Douglas notched nine and eight tackles respectively with Gentry recording six tackles for loss and two sacks.
The Bulldogs return to action this Friday night when they host the Richland Raiders in their season finale at 7:00 p.m.
