Two days after an unthinkable third-period collapse in Philadelphia, the Blue Jackets were forced to spend the entire second intermission last night at Nationwide Arena with the possibility of here-we-go-again hovering in their atmosphere.

The hard work the Jackets had invested in building a 2-0 lead was erased in a 20-second span late in the second period, when the Flyers scored twice to forge a tie.

“When I went into the (locker room), it was pretty quiet,” Blue Jackets coach Todd Richards said. “I walked out and made a comment to one of the assistant coaches. … I was expecting more energy. So I wasn’t sure what we were going to get in the third.”

The Blue Jackets got third-period goals from David Savard, Boone Jenner, Ryan Johansen and R.J. Umberger (empty-net) and pulled away for a 6-3 victory in front of a crowd of 14,090.

Umberger and Johansen had scored earlier in the game, too.

“It was just a crazy game on Thursday,” Blue Jackets goaltender Curtis McElhinney said, referring to a 5-4 loss at Philadelphia in which the Blue Jackets blew a 3-0 lead after two periods. “I don’t know how you give up five goals in a third period like we did. I hope I’m never part of anything like that again. So this was very nice tonight, to finish it out like we did.”

The night was not without loss for the Blue Jackets, however.

Right wing Marian Gaborik, playing in his first game since suffering a knee injury on Nov. 7, lasted only four shifts before he was injured again.

Gaborik suffered a fractured collarbone when he was hit hard by Philadelphia’s Zac Rinaldo and then sandwiched between Rinaldo and Flyers defenseman Braydon Coburn.

He is out two to three months and almost certainly will miss the Olympics for Slovakia. The Blue Jackets placed him on injured reserve after the game. The Jackets also lost speedy left wing Matt Calvert, who suffered an upper-body injury in the second period. He will be evaluated today.
