Asa Jackson had trouble getting onto the field in his rookie season with the Ravens, but it’s probably over.
Jackson, a 2012 fifth-round draft pick, was suspended for four games Tuesday for violating the NFL’s policy on banned substances. That means he's done for the regular season and the first playoff game.
It ends what has been a non-productive season for Jackson. He only was active for one game, playing 14 special teams plays in a 16-13 overtime win at the San Diego Chargers.
Jackson never lined up in the secondary even though the Ravens had a season-ending knee injury to Lardarius Webb and have been without his replacement, Jimmy Smith, for the last five games because of hernia surgery.
Jackson's suspension opens a roster spot for Baltimore. Linebacker Ray Lewis (triceps) could play as early as Sunday against the Denver Broncos and fill the spot, the team could sign another player or elevate a player from the practice squad.
The team isn't commenting on the situation.
