Game 3 is Tuesday at Madison Square Garden.
"Yeah, it's under control," Lundqvist said after practice Monday. "I landed on the ice awkwardly and hurt it a little bit. It's under control.
"Everybody's sore. It's the playoffs. You can't just sit out because it's hurting a little bit. It happens and you just have to make sure you do the right things to make it good."
During the first two games of the series -- both losses -- Lundqvist has allowed eight goals on 80 shots. Five of those goals came in Game 2.
"You're never happy or satisfied giving up five goals, but you have to move on and take the good parts and try to learn something from it," Lundqvist said.
