Goaltender Chad Johnson will start for the Calgary Flames. Brian Elliott, who was acquired from St. Louis on June 24, is expected to backup. He went 104-46-16 with a 2.01 goals against average and a .925 save percentage in five seasons with the Blues. "We're not in the business of making decisions based on where a guy's from or what he does," Flames coach Glen Gulutzan said. "We're going to make a decision that's best for our group. We all talked about it. We all talked about it with our goalies. Nothing was swept under the carpet. It was right out in front. We're all on the same page." Johnson is 1-0-1 with a 1.89 goals against average and .923 save percentage this season. Elliott is 0-3-0 with a 4.72 goals against average and .839 save percentage. "You can't get hung up on things," Elliott said. "Your highs can't be too high and your lows can't be too low. You have to keep an even-keel. I feel I am spitting a lot of common lines here but it's the god's honest truth." Forward Matthew Tkachuk, the No. 6 pick in the 2016 NHL Draft, is expected to be a healthy scratch. Tkachuk's father, Keith Tkachuk, spent parts of nine seasons with St. Louis. "Like any of these young guys, this is a hard league and it's good sometimes for them to sit back and look and watch the game and come back in and even be better," Gulutzan said. "We've thought he's been good, but it's part of the process." Tkachuk has one goal in five games this season.
