Wright suffered a head/neck injury at the end of the third quarter Sunday in New Orleans. The starting safety sat out practice on Wednesday and Thursday.
"It felt good (to practice)," Wright said. "I've never had (a situation like this happen before), but it's the game of football. That's what comes along with it. It's a physical game, things like that happen.
"I have no say (in whether I play). That's up to the coaches and the trainers."
A former 2008 fourth-round draft pick, Steltz made two starts in 2009, but has essentially been a special teams contributor the past four years. Teammates threw their support behind Steltz during the week when it became apparent both Wright and Harris could miss the Packers game.
"You want them to be able to trust you," Steltz said. "You have to keep going out there and have them continue to put their trust in you at practice. You have to continue to make plays, to be in the right place, to make the right checks. That's the stuff you hope to bring out to the field. The trust these guys have here at practice, you want that on the field."
