Washington Redskins free safety Tanard Jackson has been suspended without pay indefinitely by the league for violating the NFL Policy and Program for Substances of Abuse, according to the NFL.com.
This is Jackson's second ban since he came into the league in 2007, he will not be re-evaluated until 2013. He was suspended for two games in 2010 for violating the NFL's drug policy.
It's unclear what illicit substance Jackson tested positive for. He was competing against Madieu Williams and DeJon Gomes for the Redskins' free safety position.
Jackson started 10 games last season with Tampa Bay, finishing with 35 tackles and two interceptions.
