Leo Carlsson had a thigh procedure last week and his club, the Anaheim Ducks, announced he will be out for three to five weeks.
Defenseman Jonas Brodin, Minnesota, has been struggling with a lower-body injury since December and now it has flared up again.
Tre Kronor will play their Olympic debut on February 11 against Italy.
Are both definitely gone?
More or less. We'll give it a couple more days to see if anything extraordinary happens, but right now our working hypothesis is that they won't come to the Olympics, says Hallam.
“Suffer with them”
Both Leo Carlsson and Jonas Brodin played in the most recent World Cup tournaments and last year's Four Nations with Tre Kronor.
These are two fantastic hockey players and good people who look like they will miss the Olympics. I sympathize with them personally. We will move on and see how we shape our team to give us the best conditions. We feel confident that we have the depth that will make us strong.
Leo Carlsson, 21, has had his breakthrough in the NHL this season, scoring 44 points (18 goals, 26 assists) in 44 games.
Many saw him as a center on the first line of the Olympic team.
"I'd rather have a healthy player"
So it's a tough loss for the national ice hockey team.
"It's easy to get caught up in painting something that you don't know how it would have turned out. Now we are where we are. All the centers will be important, regardless of what number is on the line; we are confident that we can have four good centers in play," says Hallam.
Taking Leo Carlsson to Milan and letting him rest through the group stage to see if he's healthy for the playoffs also seems like a long shot for Hallam.
"It would be, if the medical evidence points very clearly towards it, but the question is whether it is the right way to go. Someone may have to sit out a match. If we see that the chance the players will be healthy and in full form is very small, I think we would rather take a healthy player."
A total of seven Swedes in the Olympic squad are currently injured. For the other five (defenders Victor Hedman and Erik Karlsson and forwards Gabriel Landeskog, Joel Eriksson Ek and William Nylander), things look more positive.
In the other cases, we are hopeful they will be ready for the Olympics, says Hallam.
