Knight made 12 saves in the second period, when the Kraken outshot the Panthers 13-2.
"[Knight is] unbelievable back in the goal, and we're so confident in him," Verhaeghe said. "He makes great saves every night, and it's automatic every night with him. He just continues to make highlight-reel saves."
Aleksi Heponiemi extended the lead to 4-1 at 7:49 of the third period with a backhand that trickled through Grubauer.
"Obviously, it's frustrating, but you can't focus on it," McCann said. "We have a lot of veteran guys here [which] kind of just calms us down and lets us play hockey."
Gustav Forsling scored on a one-timer from the high slot on a power play at 13:03 for the 5-1 final.
The Panthers, who were playing shorthanded with forward Anton Lundell being a late scratch, lost defenseman Radko Gudas (first period) and forward Patric Hornqvist (second period) because of upper-body injuries.
"They are both going to need to see a doctor," Maurice said.
NOTES: Verhaeghe is the fourth player in Panthers history to score twice in 26 seconds or less, joining Viktor Kozlov (seven seconds, Feb. 10, 2004), Colton Sceviour (23 seconds, March 30, 2016) and Jonathan Marchessault (26 seconds, March 23, 2017). … Ekblad's 201st assist tied Keith Yandle for sixth in Panthers history. … It was Heponiemi's second NHL goal and first since Jan. 30, 2021. … Florida forward Sam Reinhart had a five-game point streak end (two goals, five assists). … The Montreal Canadiens and Buffalo Sabres are the only NHL teams yet to defeat the Kraken.
