Tanard Jackson is about to disappear again.
Jackson won't even be re-evaluated until 2013, making this his second ban of at least one season since he came into the league in 2007. Jackson is appealing the league's decision, according to Glazer.
It's unclear what illicit substance Jackson tested positive for at this time.
Jackson, 27, was suspended for all two games of the 2010 season for violating the NFL's drug policy.
The Redskins -- who signed the safety in April -- had been waiting "a long time" to learn of Jackson's fate, according to John Keim of the Washington Examiner. Jackson had been battling Madieu Williams and DeJon Gomes for Washington's starting free safety job.
Jackson started 10 games for the Tampa Bay Buccaneers last season, finishing with 35 tackles and two interceptions. Upon releasing the troubled safety in April, Bucs general manager Mark Dominik remarked that the team was unhappy with Jackson's growth on and off the field.
Now the Redskins have to deal with the fallout of Jackson's transgressions ... for now, anyway.
UPDATE: The NFL later announced that Jackson indeed has been suspended indefinitely without pay for violating the NFL Policy and Program for Substances of Abuse.
Jackson's suspension begins immediately. He is eligible for reinstatement beginning on Aug. 31, 2013.
