The center had two assists for the Penguins who lost 3-2 in a shootout.
Malkin, who missed the second half of last season after having knee surgery to repair two torn ligaments, said he felt soreness in his knee in the Penguins' second game of the season, which was Oct. 8 against Calgary. He hasn't played since.
"Yeah, after the second period, my knee started to feel a little bit tired. I tried to skate but I can't push it, I don't know why," Malkin said. "Nothing felt wrong before the game. I don't know, it just got a little sore and I'm not feeling comfortable."
Malkin, who indicated the soreness is in the scar area from the operation, said he had a good warm-up Thursday morning and said the knee was feeling better.
