PITTSBURGH - Ben Roethlisberger's left foot is good enough to play. James Harrison's right eye is not, and he'll need surgery.

Pittsburgh Steelers coach Mike Tomlin said Tuesday he expects Roethlisberger to be under center when his struggling team faces surging Tennessee on Sunday at Heinz Field.

Roethlisberger sprained his left foot in the fourth quarter of a 17-10 loss to Houston. An MRI on Monday revealed no significant damage but Tomlin said his quarterback could be limited early in the week.

However, Harrison will be out indefinitely after fracturing the orbital bone in his right eye (it may have happened on the play in the video below). He'll have surgery this week, and there is no timetable for his return.'s Ryan Wilson notes that Harrison's backup, 2010 second-round pick Jason Worilds, is listed as doubtful with a quadriceps injury, so Lawrence Timmons will start in Harrison's spot at outside linebacker, with veteran Larry Foote replacing Timmons at inside linebacker.
