The defenseman was injured at 13:53 of the second period in a 3-1 loss to the San Jose Sharks at Scotiabank Saddledome on Tuesday when attempting to take a shot.
"Yeah, it's good," Giordano said. "You never want to sit out any games, to be honest. But got some encouraging news yesterday that there's not going to be any surgery or anything like that needed, just a little bit of time to heal. We'll go day by day now. I'm going to work hard to get back as quick as I can. ... I think it's very encouraging that my season's not lost and I can get back after the rehab process."
The Flames captain was placed on injured reserve and will not need surgery.
"We dodged a big bullet where it could have been long term," Calgary general manager Brad Treliving said Thursday. "We're going to monitor it on a week-to-week basis. I can't sit here and give you a timeline but it certainly is good news that this is not as long term as we initially feared.
"Hopefully he's back sooner rather than later. Certainly good news from where we were two nights ago thinking that this could be something that could keep him out the rest of the year."
The Flames (27-21-6), who are 2-4-1 in their past seven games, hold the second wild card into the Stanley Cup Playoffs from the Western Conference, two points ahead of the Chicago Blackhawks. Calgary hosts the Nashville Predators at Scotiabank Saddledome on Thursday (9 p.m. ET; SN1, FS-TN, NHL.TV).
"It's going to be tough, but I remember the last time I went out with an injury and the team sort of rallied around it," Giordano said, referring to missing the final six weeks of the regular season and the playoffs because of a biceps injury in 2014-15. "With the guys we have in the room … we have a better team and we have way more depth. I know the guys are going to play desperate and keep us in a playoff spot. I'm looking forward to getting back in as soon as I can, but you have to be realistic too with injuries sometimes. When you can't help the team you shouldn't play. I'll wait until that moment and go from there."
Giordano leads the Flames playing 23:57 per game.
"One of two things usually happens," Calgary coach Geoff Ward said. "You come together as a group and the guys step up together and they all start pulling the rope a little more and it springboards your team into playing harder and playing better, and you see that a lot. The other way is to let it affect you in a negative way. We've got a decision to make, obviously, but we're confident that the guys in the lineup are capable of stepping up and that they'll choose choice A instead of choice B."
Giordano is the Flames' fifth-leading scorer and highest-scoring defenseman with 27 points (five goals, 22 assists) in 54 games this season.
"If you miss a player like that, it's obviously time for someone else to step up, me included," Calgary defenseman Rasmus Andersson said. "There's six [defensemen] that are playing. We've got to step it up. It's not an easy task because of the minutes and the way he plays every night. It's tough, but the six of us have to step up as a unit."
Giordano has 479 points (134 goals, 345 assists) in 887 games through 14 NHL seasons with Calgary. He won the Norris Trophy voted as best defenseman in the NHL after he had an NHL career-high 74 points (17 goals, 57 assists) in 78 games last season.
"It'd be a lot different today if I was standing here and telling you I wasn't coming back for the whole year, I'll tell you that much," Giordano said. "There's light at the end of the tunnel and I'll be working hard to get back as soon as I can."
Calgary recalled defenseman Brandon Davidson from Stockton of the American Hockey League on Thursday. He has no points in three NHL games this season.
"Just talking with him a little, we're fine right now," Calgary forward Matthew Tkachuk said of Giordano. "We're in a playoff spot. We go on a run here and we put ourselves in a good spot. Nobody's happy with the situation or thinks it's an ideal situation, but to see how calm he is and how much he trusts in us, we'll be fine."
