The Baltimore Sun reported Jackson was suspended by the NFL for four games for violating the league's performance enhancing drug policy. The report cited a source saying Jackson tested positive for Adderall, not steroids. Jackson will be out the team's remaining three regular season games and the team's first playoff game, should the Ravens clinch.
Though the usually staunch defense of the Ravens has struggled this year (23rd against both the pass and the run), the loss of Jackson shouldn't affect them much on the field. The fifth-round pick out of Cal Poly has only seen action in three games with one tackle.
The Broncos (10-3) are in Baltimore to play the Ravens (9-4) at 11 a.m. MT on Sunday. The game will be televised by CBS.
