Redskins tight end Fred Davis, a pending free agent, faces another suspension for a failed marijuana test, according to a league source.

The former second-round pick of the Redskins has served a suspension in the past, with his off-field issues limiting his free-agent options. Set to be a free agent in March, Davis played sparingly last season and has been slowed by injuries as well after showing promise early in his career.

Davis' time in Washington could be coming to an end, with this latest suspension the latest setback.
