The Ravens have placed offensive lineman Jah Reid on injured reserve with a toe injury, and in a corresponding roster move, they have activated cornerback Asa Jackson to the 53-man roster.
Jackson had served a four-game suspension for violation of the league's policy on performance-enhancing drugs. According to the Baltimore Sun, Jackson had tested positive for the prescription drug Adderall. He was suspended on Dec. 11.
Reid's move to injured reserve ends the season for the second-year lineman, who broke into the starting lineup midway through the season at left guard. He was slowed throughout training camp and early in the season by a calf injury but started the final seven regular-season games. He was listed as questionable for the Ravens' first-round playoff game against the Colts but then was a game-day inactive. He did not practice at all this week.
With Reid out, it's almost certain that the Ravens will go with rookie Kelechi Osemele at left guard for the second straight week, with Bryant McKinnie starting at left tackle and Michael Oher at right tackle. They unveiled that lineup for the first time last week against the Colts, and the unit performed well.
Jackson, the Ravens' fifth-round pick this past spring out of Cal Poly, was a game-day inactive in the first 10 games, then appeared in three games before his suspension. He has played primarily special teams, with one tackle.
