Fairley was charged with a single count of misdemeanor marijuana possession after a small amount of the drug was found in his car during a traffic stop in Mobile, Ala., last month.
The hearing was adjourned to give Fairley's attorney more time to review the case.
His attorney told the Free Press that Fairley is in the NFL's substance abuse program and will be subject to random drug tests.
The former first-round pick is one of three Lions who have recently been arrested in marijuana-related incidents. Last year's second-round pick, running back Mikel Leshoure, was cited for marijuana possession in February and March, and offensive tackle Johnny Culbreath was also arrested in January after he was found with the drug.
All three face the possibility of suspension by the league.
