The Colts rank 29th in the league, averaging just 86 yards on the ground. But the offense has scored rushing touchdowns on eight of 19 red-zone opportunities and six out of 11 goal-to-go situations.
"Their running game is not to be taken lightly," Ravens coach John Harbaugh warned. "Their running game is much more dangerous because they know when to use it. And their running game hurts people. So you start spreading out coverages too much, the next thing you know [Peyton Manning] gets them in the right run against the right front and gashes people. They have really good running backs."
Indianapolis starts Joseph Addai (126 carries for 440 yards and six touchdowns) but has rotated in rookie Donald Brown (50-226, two touchdowns) and second-year player Chad Simpson from Morgan State (13-82, one touchdown).
Linebacker Ray Lewis said Addai will get most of the defense's attention.
"He's a first-class guy," Lewis said. "He's very good with the football in his hands. I think Brown is a good changeup for them. He is a little lighter, has little more speed and things like that. Durability-wise, I think Joseph Addai is still their guy. Brown just gives him a nice changeup."
The Colts will continue to lean on Manning, wide receiver Reggie Wayne and tight end Dallas Clark to produce, but they need production from the running attack to keep the Ravens' defense from keying on the pass.
"Some weeks, we've been able to run it and run it pretty well, but then there have been other times when we fell short of what we'd like to accomplish," Indianapolis coach Jim Caldwell said. "That's an area that we try to emphasize every week and stress the importance of it. There's that old coaching axiom that you achieve what you emphasize. We try to emphasize that, and hopefully we'll continue to get better."
Suggs: I'll be back
Speaking for the first time since getting hurt, linebacker-defensive end Terrell Suggs said the sprained ligament in his right knee isn't a season-ending injury. In fact, Suggs said he is aiming for the Nov. 29 game against the Pittsburgh Steelers.
"There is no doubt in my mind that I should be back this year," he said. "That's the plan. That's where I'm at with it."
The three-time Pro Bowl player said he hasn't seen the hit on tape but that players have told him that it was a dirty one.
"That's exactly what it felt like," he said. "But I haven't seen it, so I can't really say one way or another. I'm more upset that I'm going to miss this game. I've got to get back for that rivalry."
Heap up in the air
It's unclear whether tight end Todd Heap (chest), who missed his second consecutive day of practice, will play Sunday. But offensive coordinator Cam Cam eron expressed confidence in L.J. Smith.
"His lack of plays has been tied into the way other guys have been playing," Cameron said. "If Todd is not full speed or we need to spell him in there a little bit, we've got tremendous confidence in him."
In other injury news, defensive tackle Haloti Ngata (sprained right ankle) was limited for the second straight day. Center Matt Birk, who did not practice Wednesday because of a neck injury, fully participated Thursday. Joining him were linebackers Jarret Johnson (left shoulder) and Tavares Gooden (concussion) and quarterback Joe Flacco (knee).
Colts' secondary concerns
With cornerback Kelvin Hayden (knee) and free safety Antoine Bethea (foot) missing their second consecutive day of practice and strong safety Bob Sanders (torn left biceps) and cornerback Marlin Jackson (torn left anterior cruciate ligament) on injured reserve, the Colts might play Sunday without their entire starting secondary.
Indianapolis, which surrendered 375 passing yards and three touchdowns to New England Patriots quarterback Tom Brady on Sunday and dropped from ninth to 14th against the pass in the NFL, would seem to be a ripe opponent for the Ravens. But the offense hasn't gained more than 168 yards through the air in its past three games, and the Colts' cover-2 scheme can help rookie cornerbacks Jerraud Powers and Jacob Lacey.
"They're not just putting those guys out in cover-1 and man-to-man coverage and single coverage all day," Cameron said. "That's not happening. If that were the case, you'd say, 'OK, we can throw at the two young corners all day.' But they're not doing that. They're smart. You've got to attack this defense with all 11 guys."
Three other Colts - defensive end Dwight Freeney (hip), kicker Adam Vinatieri (right knee) and wide receiver Anthony Gonzalez (knee) - did not practice for the second straight day. Wide receiver Pierre Garcon (ankle) was upgraded to full participation after not practicing Wednesday. ... Indianapolis tight end Dallas Clark is tied for second in the NFL in catches (64) and fifth in yards (768). "You look outside of Reggie Wayne, and to me, Dallas Clark is probably the most important piece that they have on the offensive side of the ball," Lewis said. "He's just one of those class guys. He's always 'Mr. Reliable.' Even in the [AFC] championship game a couple of years ago, he made one of the most incredible catches I've seen, with perfect defense. ... You talk about Peyton [Manning], Peyton, Peyton, but Dallas Clark is probably one of his key weapons, as many great quarterbacks have always had that great tight end." ... Ravens rookie safety K.J. Gerard said he was a little surprised about being promoted to the active roster from the practice squad. "I've been working every week to try to move up," said Gerard, who replaces Haruki Nakamura (broken right ankle - injured reserve). "Under the circumstances, it's unfortunate, but I'm going to do my best." ... Running back Matt Lawrence (knee) was on crutches and has been ruled out for Sunday. ... Sunday's matchup against the Colts presents the Ravens with a three-game stretch in which Indianapolis, the Pittsburgh Steelers and the Green Bay Packers are a combined 20-7. Two losses could dash the team's playoff hopes, but Flacco said the team can't afford to look ahead. "Like you said, we're going to take it one game at a time," he said. "We understand that the rest of our games are going to be crucial for us in order to put ourselves in a spot that we want to be, and it starts with Indianapolis."
