OWINGS MILLS, Md. — The Baltimore Ravens have not adjusted their goals for this season in spite of Sunday night's deflating loss to the Pittsburgh Steelers.

Coach John Harbaugh said Monday the Ravens can still win the AFC North. But he conceded that Baltimore must play better over the next four weeks to not only make the playoffs, but to advance in the postseason.

Less than 24 hours after Baltimore's 13-10 loss to the Steelers, Harbaugh says the Ravens "have got to get better on offense," particularly on third down and in the red zone. He also says the offense needs to run the ball more efficiently and the line must better protect quarterback Joe Flacco.

The Ravens next play Houston on the road Monday night. Harbaugh says tight end Todd Heap, who pulled a hamstring against the Steelers, probably won't be ready to play against the Texans.
