IRVING, Texas -- The Cowboys need to get their struggling running game going against the Baltimore Ravens on Sunday. The Cowboys have rushed for just 128 yards the last three weeks combined.

Overall, the Cowboys are 31st in the NFL with 271 total rushing yards.

Now they face the Ravens a team that's allowed 592 rushing yards, 22nd in the league, and coming off a game against Kansas City last week where they gave up 214 rushing yards. In the first five weeks of the season, the Ravens have allowed at least 100 rushing yards in four of the games.

But inside linebacker and 13-time Pro Bowler Ray Lewis isn't backing down.

"I tell you what, they can look to do whatever they want to do, but it ain't going to be what they think it's going to be," Lewis said on a conference call with reporters Wednesday morning.

Now, Lewis wasn't trying to start anything, he was just answering a question.

But he understands the Ravens can't allow another running back to produce the numbers like the Chiefs' Jamaal Charles did. He rushed 30 times for 140 yards, but had no touchdowns.

"If you look at it per play, we're No. 3 per play, so if you take out the big plays, which every team has to figure it out, whether you go through it sooner or later, that's the business of football. We've been through this before," Lewis said.
