Chad Greenway had full participation in practice for a second straight day, another sign that the outside linebacker will play against the Bills. But before head coach Mike Zimmer gives Greenway the green light, he wants to make sure Greenway is honest about his ability to play through pain.

"Yesterday we were in pads and he felt pretty good. We've done another test to see where he's at hitting-wise and he looks pretty good, so I'm going to have to trust him with what he says," he said.

Zimmer acknowledged there is concern about Greenway reinjuring the ribs he broke in Week 2.

As for whether Greenway will start, Zimmer only said, "My thought is that if he can play, he can play."

Defensive end Corey Wootton (lower back), outside linebackers Gerald Hodges (hamstring) and Michael Mauti (illness), and tight end Kyle Rudolph (sports hernia surgery) did not practice today.

Defensive tackle Sharif Floyd, who practiced some yesterday, also sat out today with his ankle injury, though Zimmer didn't seem to be too worried about his playing status for Sunday's game.

Nose tackle Linval Joseph (ankle) and cornerback Jabari Price (hamstring) were listed as limited.

In addition to Greenway, wide receiver Cordarrelle Patterson (hip), safety Harrison Smith (ankle) and tight end Chase Ford (foot) were listed as full participants in practice for a second straight day.
