Larsson worked extensively with goaltending coach Jeff Salajko Saturday morning and has been on the ice every day.
Of course, most players prefer games to practice but Larsson is keeping the big picture in mind.
"Yeah, it's unlucky," Larsson said. "I've been over here for a month now, training with all the guys. It's sucks to miss it. I came here to prepare for this tournament, so it sucks not being here. I'd rather be 100 percent when the season starts. I think I'll be practicing with the team in a few days. It feels good."
Larsson, the Wings' sixth round pick, 167th overall, in the 2016 NHL Entry Draft, has excelled at every level since being drafted, performing well for Djurgårdens IF J20 in the SuperElit (2.24 GAA, .925 SV% in 31 games) dominating the USHL for the Tri-City Storm (1.65 GAA, .941 SV% in 30 games) and then returning after surgery to lead the University of Denver Pioneers to the Frozen Four (1.95 GAA, .932 SV% in 22 games).
So it's no wonder Larsson elected to turn pro this past April.
"First of all, I was not a true freshman," Larsson explained. "I'm 21 now. I feel like guys my age go to OHL and they got right in here and do good. I feel like I played college last year and felt like I needed to an even higher challenge for me. I felt ready. This is what I wanted to do, turn pro as early as possible. When I got the opportunity, I felt that was the right thing for me."
Larsson spent the end of last season with the AHL's Grand Rapids Griffins and then has been training the last month in metro Detroit.
"I worked with (Jimmy) Howard for a month to see how he works," Larsson said. "I worked with the goalie coach, with him. He has prepared me for what I need to do for professional hockey. It's a few new stuff. Just a few details that I had to work on. Just watching him I can see what he'd do and maybe I can take some of his game and keep what I do good."
