Wilder was found guilty by Judge Ricky McKinney, who ordered the 32-year-old to perform the community service at a local YMCA. Wilder received a 30-day suspended sentence and two years of probation.
Wilder was arrested in his hometown of Tuscaloosa in June after police found marijuana in his Cadillac Escalade. He was initially stopped for a window tint violation.
Officers searched the car after smelling marijuana and found a small amount in the vehicle’s console.
Attorney Paul Patterson said the marijuana didn’t belong to Wilder adding the boxer had just returned from a trip and others had access to the Escalade.
Wilder, an Olympic bronze medallist, is 39-0 and boasts 38 knockouts.
