"He's frustrated, as you can imagine," Treliving said. "Like all players, you go through that initial shock and disappointment, but now it's, 'OK, let's get on with it and get it better.' It's a shock for him and a bit of a loss for us.
"It's disappointing, all those things. Karri is a guy that works really hard. Players come back from these injuries, so this is something that we will see. That will be something we wait and see on. I suspect that he will train hard and heal up and be back, but he will go through rehab for sure."
Ramo, 29, was injured in the third period of a 6-5 shootout win against the San Jose Sharks on Feb. 11, in a collision with Flames captain Mark Giordano and Sharks forward Joonas Donskoi.
"It's tough," Giordano said. "He's been great for us. There's nothing much you can say -- it's a tough injury for a team to take. He played a lot of games where he was a big reason for wins. It's tough news. With that said, we need to try to rally for him and around this."
The Flames, who are nine points out of the second wild card into the Stanley Cup Playoffs from the Western Conference, host the Minnesota Wild on Wednesday (10 p.m. ET; SN1, FS-N, FS-WI, NHL.TV).
"Obviously I hope the best for them," Ramo said. "They have really big games coming up and nothing is lost yet. Playoffs are still reasonable. Obviously I'm going to be here every day and I will try to support them as best I can."
Ramo had started 34 of the past 42 games for the Flames before sustaining the injury, including two separate stretches where he started 12 consecutive games.
He tied a career-high with 17 wins, set in 2013-14, and had a 2.63 goals-against average and .909 save percentage in 37 games.
"It's a tough blow for Karri also because he's been working so hard," Calgary coach Bob Hartley said. "He bounced back from a tough start. I have no doubt in my mind that he will get back on track because he is a competitor and he's the ultimate pro.
"Even in the past few days we had strong doubts that his season was over. He was on the bike and was trying to stay positive and hoped for some miracle news. Once the doctors got to us we can't say that it was really a shock, because from first looks it didn't look very good."
Ramo is set to become an unrestricted free agent at the end of the season.
"There is nothing you can do," he said. "No need to worry about that. Like I said, the focus right now is just making sure everything goes well and that I'm ready for next year."
He didn't rule out a potential return to Calgary next season.
"We will see what is going to happen," Ramo said. "It's not a bad option."
The injury leaves veteran Jonas Hiller, also set to become an unrestricted free agent at the end of the season, and Joni Ortio, recalled Feb. 12 from Stockton of the American Hockey League, as the Flames' goaltending tandem.
Hiller is 8-6-1 with a 3.22 GAA and .889 save percentage; Ortio is 0-3-1 with a 4.14 GAA and .862 save percentage in five appearances with Calgary this season.
"We have two guys here right now and with any injury, it creates opportunities for others," Treliving said. "We're going to go with that. We're continually looking at ways to help our team. If that's for now or in the future and that won't change. Jonas and Joni are here and [Kevin] Poulin is down in the American League.
"We continue to see if we can help ourselves either now or for the future."
