The Ravens looked determined to establish the run from the start against a Titans defense that surrendered 206 yards rushing last week. But the Titans crammed the line with eight players, showing no fear that the Ravens could beat them with the pass.

Lewis totaled 9 yards on 10 carries, with 13 yards coming on one run.
"I don't know what happened," Lewis said. "Watching them on film from last week, they looked like a totally different defense."
The Ravens' defense again held its own. On the field for 33 minutes, the Ravens dug in to limit the Titans to one offensive touchdown in the game and just three first downs in the second half.
But the Ravens' defenders were more focused on the big picture after one of the most deflating losses in team history.
"Expectations are high, and they're still high," defensive end Tony Weaver said. "Nobody is hitting the panic button just yet. There are 14 games left."
The Ravens' bye week gives them 14 days to sort out this troublesome defeat before playing the New York Jets on Oct. 2.
"This bye didn't look to be at a particularly good spot when it first came out," Billick said. "But right now, it's what we need. We've got a great deal of work to do the next two weeks, plain and simple."
