Smith, Yanda questionable for Ravens

The Baltimore Ravens have listed wide receiver Torrey Smith and right guard Marshal Yanda as questionable for Sunday's clash against the New York Giants, though the two offensive starters were able to participate in a second consecutive practice on Friday.

Smith is dealing with a concussion sustained during the third quarter of last week's 34-17 loss to Denver. The second-year pro was cleared to resume practicing on Thursday, though he still must pass a baseline neurological test in order to be cleared to play.

Yanda, who sat out against the Broncos due to a sprained right ankle, also returned to Thursday's session in a limited capacity.

Baltimore, which enters Sunday's key late-season matchup clinging to a one- game lead over second-place Cincinnati in the AFC North following three straight defeats, has yet to make a determination on the status of inside linebacker Ray Lewis. The veteran team leader has been sidelined since tearing his triceps in mid-October, but has been practicing in each of the past three weeks.

Lewis is the Ravens' designated to return player on injured reserve. The team has until Saturday at 4 p.m. (et) to place the 37-year-old on the active roster to have him eligible to play against the Giants.

Baltimore is almost certain to be without two other defensive starters for Sunday's test. Linebacker Jameel McClain, who's suffering from a spinal cord contusion, was ruled out earlier in the week, while strong safety Bernard Pollard was declared doubtful due to a chest injury that also kept him out against Denver.

Inside linebacker Dannell Ellerbe, out the last three games with an ankle problem, was also termed as questionable along with fullback Vonta Leach (ankle) and backup running back Bernard Pierce (concussion).

2011 NFL Defensive Player of the Year Terrell Suggs, who's been playing through a biceps tear he developed earlier this month, and safety Ed Reed (shoulder) were among those listed as probable for Sunday's contest.
