Suggs was a game-time decision against Washington. He injured his arm in last week's loss to the Pittsburgh Steelers after missing the first six weeks of the season with a torn Achilles tendon, which he suffered last April.
Suggs hurt his arm with about five minutes left in the game, getting around the corner to tackle Isaac Redman.
Ravens coach John Harbaugh erred on the side of caution with the reigning NFL Defensive Player of the Year, hoping his injury-riddled defense could survive Sunday's scram against Robert Griffin III and the Redskins.
Today's game is the first in nine years that did not feature either Suggs or Ray Lewis, who is also rehabbing a torn triceps.
Suggs could return next week against Denver, according to Harbaugh, as his injury looks less severe than the one that sidelined Lewis for most of the season.
Suggs' injury could not come at a less opportune time as the Ravens face off today against the surging Redskins and next week play Peyton Manning and the Broncos, who have won eight in a row—and who are in a four-way battle for the No. 1 seed in the AFC.
While the Texans once looked like a near-lock to secure home-field advantage throughout the playoffs, the Ravens, Broncos and Patriots each have only three losses, and the Texans and Patriots face off tomorrow night.
Baltimore will need all its defensive firepower to stifle Manning, who is playing better than any quarterback in the league.
Several players have played through such injuries, including Miami Dolphins linebacker Karlos Dansby, but the severity of the injury varies.
