It is possibly paving the way for Campbell's first action since March 14, when he was hit by Capitals forward Alex Ovechkin.
Campbell suffered a fractured clavicle and rib in that collision, which cost the Washington Capitals' star a two-game suspension, handed down by the league.
The Predators own a 2-1 series lead, and Blackhawks coach Joel Quenneville was asked whether trailing in the series dictates Campbell's return.
"It's a good question," he said Thursday morning. "It's tough to measure something like that.
"When you're ready to play, you're ready to play. When you talk to players that have been out for a while, they know their body, they know when they're ready. We'll see."
This is the first time since that injury that Campbell has been listed as a game-time decision.
"It's up to myself, the doctors and the team," Campbell said. "Obviously, I'm feeling pretty good and getting closer to that timetable."
When asked about being nervous about his first hit, Campbell said: "Looking forward to it. Should be fun."
