Kovacevic, realizing the play was still alive, scored on a 200-foot shot into the empty Lightning net.
"The building was loud, so I couldn't hear if there was a whistle or not," Kovacevic said. "I saw that no one was really in the area for the whistle to go, so I said 'Let's go, let's play it'. I saw the goalie go in for a skate and … I might as well shoot it. I was pretty sure he didn't blow the whistle and we could just catch them by surprise."
Cooper said it was one of the strangest things he had ever seen in the NHL.
"You go into every single game and you never know what you're going to see," Cooper said. "That was a first. The big thing I learned is that Johansson leaves the net early when he thinks the whistle was blown. I guess you can make light of it now."
The goal appeared to give Tampa Bay a new burst of energy and led to more zone time and scoring chances.
Point cut it to 2-1 at 14:01 with a shot from the slot off a pass from Nicholas Paul.
Austin Watson tied it 2-2 at 17:36 when he lofted the puck toward the net and Montembleaut misplayed it off the bounce.
"I thought the whistle was blown and the music was playing and all," Johansson said. "At the end I felt like it gave us some energy. We came back and won the game and that's the biggest thing. The whole team played better after that situation."
Calvin de Haan put the Lightning ahead 3-2 at 7:49 of the third period when he beat Montembleaut with a shot to the far post. It was his first goal of the season.
