There was no update from the Jets after Laine left the morning skate.
"Patty couldn't warm up right during practice," coach Paul Maurice said Sunday. "I don't even know if I'm going to list him as day to day yet. We'll wait until we get to tomorrow to see how he's feeling."
Laine scored two goals, including the overtime winner, and had an assist when the Jets opened their season with a 4-3 victory against the Calgary Flames in Winnipeg on Thursday.
The Jets practiced Sunday after practice was canceled Saturday "out of an abundance of caution due to potential exposure to COVID-19," they said.
"I didn't have to cancel practice yesterday," Maurice said. "So that was just our decision, abundance of caution. My understanding is that there's about five or six different things that will put you into the protocol. And the results of those are different. ... I'm not allowed to tell you why a guy went in, but I can give you an example.
"If you had a sore throat today and said, 'My throat's a little sore,' you're out. And you're out of the room and you're in the protocol. We'll test you out and you continue to test negative, and you know what, and your symptom disappears, then you're no longer part of it."
Winnipeg begins a three-game road trip with the game against Toronto before playing at the Ottawa Senators on Tuesday and Thursday.
Maurice said Winnipeg will be without defensemen Dylan DeMelo, whose wife gave birth to a baby boy Thursday, and Tucker Poolman, who is in COVID-19 protocol, for the road trip.
He also said forward Nikolaj Ehlers, who didn't practice Sunday because of injury or illness, will travel with the Jets and is expected to be available to play against the Maple Leafs.
