Updating an earlier report, U.S. National Junior Team forwards Brock Nelson and Jeremy Morin were on the ice for the team picture Monday, but immediately left prior to the start of practice.
No one from USA Hockey would provide an update on the injuries, although TSN reported that both players are considered day-to-day with upper-body ailments.
When asked to comment on the extent of the injuries, coach Keith Allain said, "I'm not commenting on injuries."
U.S. forward Ryan Bourque was asked if the team would have to make some major adjustments if Nelson, a prospect of the New York Islanders, and Morin, who played in the NHL with the Chicago Blackhawks this season, were sidelined for an extended period of time.
"I can't really comment on it and everything's day to day," Bourque said. "I don't know much anyway. I think depending on what happens in the next few days, we'll see and obviously that's part of the tournament. Guys are going to have to step up and guys will be held accountable. We'll see what happens."
Chicago coach Joel Quenneville was asked about Morin following his team's morning skate on Monday.
"I don't know anything. I didn't see the play," he said. "I didn't hear exactly how he was hurt, but I heard it was an upper-body injury. Whatever the case, I'm sure we're going to do what's best for the kid. I'm sure that's what the plan is, but I haven't heard."
Quenneville also said he didn't know whether or not the injury would sideline him the remainder of the tournament.
On the Canadian front, coach Dave Cameron named Olivier Roy his starter for Tuesday's game against the Czech Republic. Roy made 24 saves, including all seven in the third period, when Team Canada earned a 6-3 decision over Russia on Sunday.
Cameron was noncommittal when asked if Mark Visentin would get the nod against Norway on Wednesday.
"We'll go game by game and Mark will get in at some point," Cameron said.
Roy is excited about getting another opportunity.
"It's another great challenge and we have a great team for sure," Roy said. "We have to get ready for that next one.
"We knew entering camp that it would be a battle for spots on this team. It was pretty exciting playing (against Russia) but as the game went on, the excitement went down and I settled down. It was great to play in that game."
