PITTSBURGH—Williams said he feels confident he'll get another chance at some point this season.
"You know what, they wanted to make sure everything is rested up," Williams said. "They wanted to let Jah get the opportunity. Absolutely, there will be more opportunities for me."
Big game for Graham
Starting his second game in a row with cornerback Jimmy Smith sidelined following sports hernia surgery, Corey Graham intercepted Steelers quarterback Byron Leftwich once.
He also recorded eight tackles and a game-high three pass deflections.
"Corey Graham came up big," Harbaugh said. "He played really well."
Added Graham: "That's how it is. When you have injuries, the next guy has to step up and I was fortunate enough to get the opportunity to play with Ed Reed and Chykie Brown and you just got to step up and make plays. The game's not going to stop, and the team's not going to stop. We have to find a way to fit in and find a way to get it done."
The Pro Bowl special-teams ace also delivered a big hit on unsuspecting Steelers tight end Heath Miller late in the game to help preserve the win.
"I tried to go out there and make plays, and I was fortunate," said Graham, who intercepted three passes last season with the Chicago Bears. "He didn't see me coming and instead of going for the ball, I went for the hit."
Meanwhile, backup safety James Ihedigbo delivered a punishing hit on his sack of Leftwich on a delay blitz.
"It was a zone pressure," Ihedigbo said. "I was supposed to come outside, and I saw it open up. I went for it and made a good play. That's what I'm here for, whatever I can do to make an impact. I was glad that I did and helped our team."
The Ravens' oft-maligned defense held the Steelers to 10 points as Leftwich completed just 18 of 39 passes for 201 yards and no touchdowns for a 51.3 quarterback rating.
The Steelers were held to 17 first downs and 311 yards of total offense, progress for a defense that has struggled to stop people this season.
"We got to find a way to go out there and get it done," Graham said. "We haven't been playing the best the last couple weeks, or the whole season some people say, but we have to find a way to get wins and that's what we were able to go out and do today."
R. Lewis in the house
Injured Ravens middle linebacker Ray Lewis made his presence felt on the sidelines, waving around his surgically-repaired right arm in a way that suggests his recovery is going well.
On injured reserve-designated to return, the former NFL Defensive Player of the Year flew into Pittsburgh on Sunday to attend the game.
Before kickoff, Lewis exhorted his defensive teammates to get them fired up.
After the game heading into the locker room, Lewis said loudly: "That's how you finish."
Lewis could return at some point this season despite undergoing surgery for a torn right triceps suffered against the Cowboys.
