Brian Elliott lay sprawled on the ice, and as he sat up, the crowd of 18,681 at Scottrade Center late Thursday night began chanting: “ELL-I-OTT! ELL-I-OTT!”

The goaltender’s name reverberated throughout the rink, but it wasn’t the customary cheer that follows a big save. Sure, Elliott did deny the driving attempt by LA’s Dustin Brown, but that’s not why folks broke into a spontaneous chorus. He was shaken up on the play, and fans worried about his well-being.

“It was almost like a movie,” Elliott said Friday. “I wanted to tell them, ‘Give me some time, hold on here.’ When you know you have the rink behind you, it feels pretty good.”

The incident occurred with 10 minutes, 51 seconds remaining in regulation of Game 2 Thursday. Elliott eventually rose to his feet, made the final five of his 28 saves and, on Barret Jackman’s last-minute goal, picked up this second win of the Western

Conference quarterfinals in a 2-1 victory over LA.

“It definitely didn’t feel good right away, but I was able to continue,” Elliott said. “You get the first shock of pain, but it’s obviously just kind of skating it off there and it felt good. Nothing more to it.”

The Blues shook off the Kings and now lead two games to none in a best-of-seven series that shifts to Staples Center tonight for a 9 p.m. face-off. Following Thursday’s scare, Elliott will open Game 3 in the goal, making his 11th consecutive start for the Blues.

“If a guy that’s important to your team is down, laying face down, you’re obviously worried about him, but he popped up and I’m sure the Elliott chants from the fans helped him up a little bit,” Jackman said. “He’s a huge reason that we’re in the playoffs, and then the last two games, he’s really stood on his head at the moments that we’ve needed him, giving us an opportunity to be in a position where we’re up 2-0.”

This isn’t “like a movie.” This is a movie.

Tonight, the Blues will be returning to the site of the carnage, a 6-4 loss to LA on March 5 in a game that the club led 4-1 in the second period. Jaroslav Halak gave up five goals on 21 shots before Elliott came in for mop-up duty, surrendering one goal on eight shots.

Here’s how confident the Blues were in Elliott at the time: Rookie Jake Allen was recalled from Peoria within an hour of the defeat and started the team’s next game in Phoenix two nights later. Elliott didn’t see the ice for 11 straight games.
