Steelers tight end Heath Miller suffered a setback with his concussion and did not practice today, which leaves his status for Sunday's game against the New York Jets in doubt.
Miller missed last Sunday's game against Cincinnati because of a concussion he sustained on Dec. 5 at Baltimore.
He practiced for the first time since then on Wednesday, but sat out today when he experienced a mild headache.
"He experienced a little headache," said offensive coordinator Bruce Arians. "Very cautious. We're not going to take any chances with him."
Arians said he hopes Miller can practice on Friday and play on Sunday but they will not take any chances.
"I sure have my fingers crossed, I hope so, but we're going to do what's in his best interests, his family's. We're not going to force anything. He's smart enough to make the right decision."
