The Steelers called the injury a bone contusion and that Roethlisberger is "day-to-day."
"I did not see it," said Coach Bill Cowher. "I think he got rolled into."
The Steelers haven't made a determination on Roethlisberger's status for Sunday's game at Baltimore. He'll be evaluated further Thursday.
Cowher was terse with reporters during an impromptu post-practice gathering. When asked whether he liked how his team practiced, Cowher said, "not really."
Kendrell Bell (groin), Chad Scott (groin) and Chris Hoke (arm) missed Wednesday's practice. Bell is questionable for Sunday's game and Scott is probable. Hoke, who has a staph infection and is doubtful for the game, was back with the team and on the sidelines.
The Ravens' injury report lists back-up left tackle Ethan Brooks (knee), center Mike Flynn (clavicle) and nose tackle Kelly Gregg (knee) as out. Wide receiver Travis Taylor (groin) and left tackle Jonathan Ogden (knee) are questionable, and cornerback Gary Baxter (hand) is probable.
Deion Sanders, 37 and out of football for three years, played "15-16" snaps as a nickel back for the Ravens last Sunday against the Cleveland Browns, according to Ravens coach Brian Billick, who's not worried about Sanders' conditioning.
"I have seen a lot of commentary by a lot of people that are making a lot of observations about where this man is physically that aren't qualified to do so," Billick said. "He looks pretty good. He's in tremendous shape.
"You worry about all your players holding up under the grind in a 16-week season, but he seems to be in excellent shape and we are continuing to dole out his responsibilities. He took 15-16 snaps the other day. With the amount of three wides I would anticipate seeing from Pittsburgh, which is a standard part of their progression, I imagine he could see anywhere from 20-25 snaps this game."
Antwaan Randle El expects Sanders to cover him most of the time.
"I'm expecting him to cover me because of our sets," said Randle El. "He looked pretty good on the film we watched."
QUOTH THE RAVEN
- Ravens All-Pro middle linebacker Ray Lewis was asked about a variety of topics. Here are a few of his replies.
- On losing Gregg, the Ravens' nose tackle: "That effect is personal. That is my bread and butter. Kelly Gregg is the one who makes me run and tick, and he is not going to be there so you know that we are going to have to go to a younger guy."
- On stopping NFL touchdown co-leader Jerome Bettis: "If you keep getting in those one-yard situations, I can't stop them anyway. One yard is one yard." On having Kordell Stewart on his team: "It is definitely different. You know that this is a guy that I have been playing against for years in some classic battles. And if I'm correct, he won the majority of them. The thing is just having him now. He is so versatile and he has so much knowledge of the game. Everybody goes through up and down years, however we want to weigh them out. But this guy is a guy that has been there. He has taken Pittsburgh to championship games so it's just great to have him around."
