Antonio Brown is expected to miss at least two more weeks.
Brown has been out since suffering an ankle injury in Week 6, but he is now apparently dealing with a different injury.
"It was more a different injury than originally thought," Bruce Arians said. "A sprain. There's some issues in the heel -- that's what he's having problems with."
In five games this season, Brown's had 29 catches for 418 receiving yards and four touchdowns.
