The NFL has denied Josh Gordon's petition for reinstatement from his indefinite drug ban.

Gordon can apply for reinstatement again later in the year.

The league will need to see a serious commitment from Gordon to his program, including a possible stint in an inpatient rehab facility.

Mike Garafolo of Fox Sports reported that Gordon had failed another league-administered drug test.

The amount of marijuana in the samples was less than the 35 nanograms required for a positive test, according to the report. But a diluted sample that contains traces of a banned substance constitutes a positive test for a player in Stage Two or Stage Three of the program. Gordon is in Stage Three.
