A judge sentenced the 45-year-old to three years of supervised probation. He pleaded guilty Dec. 11 to theft-related charges.
Authorities say Dumas stole about $800 worth of merchandise from a Luke Air Force Base store while working with a janitorial service in 2012.
They say Dumas was seen on surveillance cameras taking cigarettes, alcohol, food, DVDs and shoes.
Dumas originally pleaded not guilty to eight felony charges of organized retail theft. He later reached a plea agreement.
Dumas played for the Suns from 1992-1995 and helped Phoenix reach the NBA Finals in 1993. He was waived by the team after missing a drug test.
