Kuemper, 27, served as Antti Raanta's backup vs. Calgary and watched his new team lose, 5-2, to end a season-long four-game winning streak. With home games vs. Anaheim and Vancouver set for back-to-back nights this weekend, Kuemper likely won't be a non-participant for long.
"We're going to take it one game at a time," Head Coach Rick Tocchet said. "'Rants' is playing really well. I don't want to wreck that ... but obviously Kuemper is here to play (too). He's not here to sit."
Kuemper posted a 10-1-3 record this season before the trade and a 2.10 goals-against average in 19 games, including 15 starts.
"I think he's a great goalie, from what I've seen this year," Tocchet said. "I don't know a lot about him, but when you have a big goalie that can move like that the sky's the limit ... I'm not saying he's going to be Matt Murray, but the way his body (is) and the way he moves out there, he looks like a little Matt Murray out there."
• Derek Stepan and Kevin Connauton scored goals for Arizona in the loss to Calgary, but their goals bookended five goals scored by the Flames.
It was a disappointing effort by a team that had four days off since its previous game.
"We were off as a group all night," Stepan said. "That happens in an 82-game schedule. I think we can do a better job managing it. Give them credit, when they got opportunities they scored. You've got to flush this one down and get ready for back-to-back (games) on the weekend."
