Frederic was injured on Nov. 9 when he took a booming open ice hit from Ottawa's Josh Brown in the neutral zone, though the 23-year-old acknowledged that it was the aftermath of the check that did most of the damage.
"Right away my vision was a little funky there," said Frederic. "I had some headaches, but it was mostly my vision. I guess if you hit the back of your head, that's your vision. It wasn't really the hit. That was fine. It was when I hit my head on the ice. I felt fine when I got up to skate and then the lights kind of went down and I knew I had to get off."
Craig Smith, who has two goals and four points over his last four games, appears to be getting back to full strength himself after missing time earlier this month due to an undisclosed injury and was reunited with Taylor Hall and Charlie Coyle during Saturday's skate. Tomas Nosek, meanwhile, shifted back down to his familiar fourth-line center role between Anton Blidh and Curtis Lazar.
"We'd like to reward the effort players, guys that have been in the league, needed some time," said Cassidy. "But if Freddy can bring a little bit more of a motor in the middle of the ice - and Kuhly played hard, effective hockey when he was in, we just ran into some numbers eventually. Maybe it's time for them to go back in and appreciate their spot in the lineup and work hard to keep it type of mentality. It can be a hard-working line.
"We know Nosey, no matter who he plays with, does a good job defensively…typically he's very responsible, he's played well with Blidh and Lazar in that role. Just moving pieces around."
With all the new trios up front, it appears that Erik Haula and Jake DeBrusk would be the odd men out against the Canucks.
"[Haula's] game right now, we need more compete out of him," said Cassidy. "He tends to get moving more in the middle. We haven't seen him on the wing. I can't rule it out, but right now we have an abundance of left-shot wingers. In the middle, that's what he was signed for to sort of anchor that line. It hasn't worked out as well as we'd like."
