The charge was in connection with a Dec. 31 DUI arrest. The Arizona Republic reported Barkley, 45, will have five days of his jail sentence suspended if he completes an alcohol treatment program.
When he was arrested, Barkley's blood-alcohol level was reported to be .149, nearly twice the legal limit of .08 in Arizona.
Barkley took a leave of absence from his job as a basketball analyst with cable network TNT. He rejoined the "Inside the NBA" studio show last week, issuing an on-air apology for his DUI.
