Jarret Johnson, Jimmy Smith upgraded to full practice

The Ravens got some good news on the injury front. Starting outside linebacker Jarret Johnson and rookie cornerback Jimmy Smith participated fully in Friday's practice.

Johnson had sat out Thursday's session with a lingering back ailment, but he has played in 118 consecutive games, which ranks as the longest streak in Ravens history and the fourth-longest active streak in the NFL.

Smith, who hasn't played since suffering a high left ankle sprain in the season opener against the Pittsburgh Steelers on Sept. 11, was limited Thursday. Another strong day of practice Saturday, and the first-round pick could be available for the team's contest against the Jacksonville Jaguars Monday night.

Cornerback Chris Carr (left hamstring) was limited for the second straight day.

Starting strong safety Tom Zbikowski joined two other starters in wide receiver Lee Evans (left ankle) and starting left guard Ben Grubbs (strained ligaments in right toe) in sitting out Friday's practice.

Zbikowski, who practiced on a limited basis Thursday, has been dealing with symptoms stemming from the concussion he sustained in the Ravens' 34-17 victory over the New York Jets on Oct. 2. As of Thursday, he had not yet been cleared for contact, according to coach John Harbaugh.

Inside linebacker Dannell Ellerbe (hamstring) and rookie running back Anthony Allen (thigh) have already been ruled out for Monday night.

For the Jaguars, Eben Britton (back) did not practice for the second straight day. Britton is a starting left guard who was supposed to start at right tackle last Sunday against the Pittsburgh Steelers before being sidelined by a flare-up.

Strong safety Dawan Landry, a former Raven for five seasons, was downgraded to limited participation after fully practicing on Thursday. Landry was listed as dealing with a thigh injury.

Jacksonville did upgrade 12 players from limited to full participation, including a several starters in running back Maurice Jones-Drew (non-injury related), left tackle Eugene Monroe (shoulder), right tackle Guy Whimper (hip), fullback Greg Jones (non-injury related), defensive end Aaron Kampman (non-injury related), defensive tackle Tyson Alualu (knee) outside linebacker Clint Session (elbow) and cornerbacks Rashean Mathis (non-injury related) and Derek Cox (groin).
