The Panthers went 0-for-6 on the power play, including a 5-on-3 for 1:35 midway through the second period during which they generated three shots.
"There's going to be a bunch of opportunities to look and say, 'If that had gone, what would have happened?'" Florida coach Paul Maurice said. "You know what? [The Blackhawks] played well. They defended well, they blocked shots, they got in the lanes."
Chicago coach Luke Richardson said the penalty kill gave the team a "huge boost."
"Like our willingness to sacrifice for our team and our goalie, and especially the second period was huge," Richardson said. "But even the third period in a crucial time in the game, blocking shots, guys are standing up and [on the] bench cheering. It becomes contagious, and then it continues into the 5-on-6 situation, which is like a penalty kill. I think it becomes like a bit of an identity for us that we're willing to do."
Blackhawks forward Tyler Johnson left early in the third period after he was hit into the boards by Aleksander Barkov.
"Not good tonight, but we'll know more tomorrow," Richardson said. "He's been so good for us. We just hope it's not really long. You know he's a tough cookie. He's been great statistically for us, but watching him play away from the puck this year has been really inspirational for younger players on the team, and he's leading by example.
"He's not a big guy (5-foot-8, 185 pounds), but he's physical. And he's a presence, he's a voice. He's got the experience of winning and what it takes to win, so definitely if he's out for a bit, we're going to miss that. We're just crossing our fingers tonight for that."
NOTE:Kane's goal in the first period was his 800th even-strength point. He is the third active player to reach the mark, joining Sidney Crosby of the Pittsburgh Penguins (896) and Alex Ovechkin of the Washington Capitals (879), and the third player in Blackhawks history, along with Stan Mikita (987) and Bobby Hull (806).
