Asa Jackson suspended eight games for violating NFL’s performance-enhancing drug policy

Ravens cornerback Asa Jackson has been suspended for the first eight games of the season for violating the NFL’s policy on performance-enhancing substances, the league announced Friday.

Jackson, 23, is a second-year pro who was selected in the fifth round of the 2012 draft. He appeared in three games as a rookie, but was also suspended four games last year for a violation of the same policy.

Jackson isn’t expected to be a key figure in the Ravens secondary with a healthy Lardarius Webb rejoining Corey Graham and Jimmy Smith.
