Johansson, who sat out Games 2 and 3, met the team on Tuesday morning after staying away for several days in order to prevent the spread of whatever was ailing him. The winger practiced in his familiar third-line left wing spot, alongside Charlie Coyle and Danton Heinen.
"Just got sick real bad, not much you can do about it," said Johansson, who also took reps with the second power-play unit. "It is what it is. It's bad timing and not a fun part of the year to get that...feeling better now. Good to be here with the team and be able to skate.
"It's moving in the right direction. It was good to be out there today and get a little sweat in. Hopefully [I'm in for Game 4]."
Moore, meanwhile, has not played since March 25 in Tampa Bay when he suffered an upper-body injury after a heavy hit into the boards from Lightning forward Adam Erne.
"We've kind of targeted this time," said Moore, who was partnered with Matt Grzelcyk during Tuesday's practice. "We were able to get ahead of it and have a timeline and kind of exceeded expectations. I feel really good and hopefully be ready to go tomorrow."
The blue liner was off the ice for nearly 10 days following the injury, but was able to work out in the gym and ride the stationary bike to keep up with his conditioning. The toughest part, Moore said, was having to watch the first three games of the postseason from afar.
"It's difficult, especially being in a close series like this, to be removed from any possible contribution. It's really tough to sit and watch," said Moore. "But you try to be a good teammate and make sure that you're bringing good energy around the guys and when you come into the rink, working hard and pushing guys."
Sean Kuraly (hand) joined the team toward the end of Tuesday's practice, but is not yet ready for game action, per Cassidy. Connor Clifton was on the ice for the full session in a maroon non-contact jersey.
