PITTSBURGH (AP) - Pittsburgh Steelers tight end Heath Miller has missed practice due to an exercise-related headache, putting his status for Sunday's game against the Jets (9-4) in question.
Miller sustained a concussion Dec. 5 against Baltimore, causing him to miss last week's game against Cincinnati. Ravens linebacker Jameel McClain was fined $40,000 for the helmet hit.
Miller was cleared to resume practicing and did so Wednesday, only to be held out of Thursday's practice.
The Steelers (10-3) went through a similar situation last season with quarterback Ben Roethlisberger. He was cleared to play against the Ravens, but was held out after experiencing post-concussion headaches.
Linebacker James Harrison sat out practice for a second successive day with an undisclosed illness.
