Wallace has talked about probably being a little tired after his first few practices with the team, so he'll need to work off the rust before contemplating playing in the season opener.
Despite needing some time to get readjusted, Haley thinks Wallace can potentially make it back in time, according to the Pittsburgh Post-Gazette.
"You're talking about a guy who's a wide receiver, a pass-catcher," Haley said. "It's not a running back or someone who has to be in the action of the game. I think it's feasible he's ready to go when we start this thing up."
