Coach John Harbaugh said both injured linebackers might be available to play when the Broncos come to M&T Bank Stadium on Sunday.
Harbaugh said Suggs was close to being able to play Sunday, but the decision to sit was made between the two near game-time because of the wet conditions.
So Suggs has missed one game because of his torn right biceps, but he might not sit out another.
"He's got a good chance to play," Harbaugh said.
Lewis hasn't played since tearing his triceps Oct. 14 against the Cowboys. He has been rehabbing in Owings Mills and practiced last week.
But this is the first game he will be eligible to play after being placed on injured reserve with a designation to return.
"There is a chance (Lewis plays)," Harbaugh said. "He's making good progress. We'll just have to see how he practices this week. I look forward to Wednesday. We'll know a lot more."
Harbaugh provided updates on the Ravens' other ailing players as well.
Offensive lineman Marshal Yanda suffered a "somewhat serious" sprained ankle. The team will monitor it throughout the week. Linebacker Jameel McClain (neck) needs to undergo testing, but is expected to be good to go.
Tailback Ray Rice suffered a left hip bruise, but should be able to play. Running back Bernard Pierce strained his lower back, but should be fine. So should defensive end Arthur Jones (bruised shoulder) and defensive end Pernell McPhee (groin).
Safety Bernard Pollard continues to play through a rib ailment. Fullback Vonta Leach sprained his ankle.
Tight Ed Dickson, who missed his second straight game with a knee injury, ran Monday and will have a chance to play. Cornerback Jimmy Smith (hernia) will also have an opportunity to return.
