Arnott a go: After choosing to stay home from Sunday's game in St. Louis, Arnott said he expects to play tonight in Chicago.
Arnott had decided to avoid playing back-to-back games last weekend in order to rest his right knee, on which he had surgery Nov. 22.
Trotz said he expected that Arnott would play in the back-to-back games this week, which includes hosting Buffalo on Thursday.
Upshall update: Predators right wing Scottie Upshall, who has missed the last 17 games with a groin strain suffered at Columbus on Nov. 15, has started skating on his own but is still about two weeks away from returning, Trotz said.
