PITTSBURGH (AP) - Ben Roethlisberger’s sprained left foot might be the least of the Pittsburgh Steelers‘ problems.

Coach Mike Tomlin expects his quarterback to play on Sunday when the struggling defending AFC champions host Tennessee (3-1).

The same can’t be said for linebacker James Harrison, who needs surgery to repair a fractured orbital bone near his right eye and will be out “for a number of weeks.”

Harrison sustained the injury in the third quarter of Pittsburgh’s 17-10 loss to Houston last week when the forepad in his helmet came down and struck him in the eye as he collided with a Texans player.

The 2008 NFL Defensive Player of the Year returned to the game, but was ineffective at times as Houston drove the length of the field to score the winning touchdown.

The 33-year-old groused the Steelers (2-2) “stink” afterward but gave no indication of significant damage. Tomlin indicated he won’t know how long Harrison will be out until after the surgery.

“I told y’all it’s wasn’t a concussion!! Lol I’ll be ok in time,” Harrison tweeted on Tuesday shortly after the announcement.

The Steelers will slide Lawrence Timmons over from his inside linebacker spot to replace Harrison and start veteran reserve Larry Foote in Timmons’ place.

Not exactly the way the Steelers wanted to start a pivotal stretch. They have been manhandled in losses to Baltimore and Houston and were relatively unimpressive in wins over woeful Indianapolis and Seattle.

Tomlin stressed the need to return to fundamentals after his team allowed Houston’s Arian Foster to rack up 155 yards, the most the team has surrendered to a single back in nearly eight years.

Getting back to basics while putting familiar faces in somewhat unfamiliar places will be difficult, though the defensive line should get a jolt from nose tackle Brett Keisel.

The veteran is expected to play after missing the past two weeks with a knee injury. Yet Tomlin isn’t hailing Keisel’s presence as reason to think the defense’s problems stopping the run are over.

“We have capable men who play who need to do a better job,” Tomlin said.

And do it better quickly.

The Steelers are second in the league in yards allowed but are 22nd against the run, giving up a whopping 4.8 yards per carry, well above the 3.0 yards per attempt they gave up last season.
