That afternoon, Dupuy suffered two cracked vertebrae when thrown from a horse in the starting gate.
Dupuy was about to ride We Be Boppin in the seventh race of the afternoon card.
"The horse was loaded into the gate and was standing good," Dupuy recalled. "A couple of other horses then caused a commotion and my horse flipped faster than any others I've experienced."
When injured, Dupuy had ridden 202 horses at Charles Town Races in 2000 and logged 36 wins, 24 second-place finishes and 22 third-place finishes. His in-the-money percentage was 40.59 and win percentage was 17.82.
He won more than 3,200 races during his career.
Dupuy was still on the sidelines in August when he heard about the opening at Mountaineer Park.
"The timing was just right, everything in life is about timing," Dupuy said. "Here I was on the sidelines and I heard about a job opening at Mountaineer Park. I felt I should give it a look."
Dupuy journeyed to Mountaineer Park on Aug. 28.
"I went up there that day for an interview and they called me last week saying I was selected, pending the approval from the governor," Dupuy said.
Current Charles Town-based steward Danny Wright will spend a month at Mountaineer Park while Dupuy works at Charles Town under the guidance of Frank Utterback and Bobby Lotts.
Dupuy, who attended the stewards accreditation school in Louisville, Ky. in 1996, will start his new duties at Charles Town Races on Oct. 1.
Dupuy listed Mighty Ben, Bold Ben, Turn Capp and 'the last winner I rode' as his favorite horses.
"I rode many good ones," Dupuy said when reflecting on his race-riding career.
