Since the trade, Soshnikov had been waiting in Toronto as paperwork for his U.S. visa was being completed. He said the extra free time gave him a chance to get to know the Blues better.
"It was a great opportunity to watch the team's structure," Soshnikov said. "I was watching a few games, so it gave me a little bit more information before I got here."
At Saturday's practice, Soshnikov was skating on a line alongside Alexander Steen and Patrik Berglund.
"Hard, physical. I go for the forecheck, go to the net, create some offense, too," Soshnikov said when asked to describe his game. "Just play hockey. We'll see how it's going to play out for me here. Games (are) going to tell how I'm going to fit in, but I'm going to try and do my best, play hard and be a good teammate."
Yeo said he expects Soshnikov's addition will inject some energy into his lineup.
"There's no question (it will)," Yeo said. "You could see there was a little bit of excitement, and obviously when you add a guy like that, it gives you the ability to shuffle things around a little bit, makes you a little bit deeper and a little bit stronger through your whole lineup… The only way for him to get fully up to speed now is to start playing hockey, and so we might as well get him in quickly."
