Hawks coach Joel Quenneville said he is "absolutely" monitoring Niemi's mental state as the rookie battles for more playing time.
"I don't think that the distraction of getting a little bit more responsibility has changed him at all," Quenneville said. "The best way to measure that is to see how he is playing in the net. You're not going to get that read because he is pretty consistent in his mannerisms or how he approaches games.
"We are getting to see a little more out of him now and you get a better read as you go along. We like what we see and, for a young kid in the net, it's been a good year for him."
* Quenneville said it's likely the Hawks will field a similar lineup Saturday as they had against the Kings on Wednesday, where Tomas Kopecky, Colin Fraser and Jordan Hendry were healthy scratches.
* The Hawks signed defenseman Ryan Stanton Friday to a three-year entry-level contract, which begins next season. Stanton, 20, has 40 points in 57 games for the Western Hockey League's Moose Jaw Warriors.
