Heath Miller Miller remains on the physically-unable-to-perform list after having offseason surgery to repair three ligament tears in his knee, including the anterior cruciate ligament. The Steelers have not set a timetable for his return, but he appears to be on a schedule similar to the one Rashard Mendenhall was on in 2012 when he came back from offseason ACL surgery.
Spaeth, re-acquired in free agency to be Miller's backup, had surgery Monday to repair a Lisfranc sprain in his foot -- an injury that will keep him out at least eight to 10 weeks.
"We'll keep him alive and see what the timetable is for him," coach Mike Tomlin said. "I'll probably get more clarity with that over the next couple weeks."
This year, the Steelers bye comes the week after their fourth game in London against the Minnesota Vikings. So it is conceivable Miller will return at least by the Oct. 13 game against the New York Jets, if all goes well.
