Jonathan Toews faces Kings
"He's fine," coach Joel Quenneville said. "He's playing. He's ready to go."
Quenneville said he would be watchful of Toews and how he reacted to playing on Saturday.
"I know Johnny will be used in all situations," Quenneville said. "We'll keep an eye on his minutes and basically gauge on how he's feeling. If he gets fatigued a little bit, we'll cut back. But hopefully he's ready to go his usual workload.
"I think he's beyond (the flu). The game takes over. I think everybody's targeted today's game and everybody's excited. I'm sure he's excited about getting started as well."
Toews finished fourth on the team with 57 points last season. He had 29 goals and 28 assists. He's recorded 50-plus points in all five of his NHL seasons.
Toews is already the second Blackhawks player to be struck with the flu. Marcus Kruger had it earlier in the week and missed two practices.
The Blackhawks will travel to play the Phoenix Coyotes on Sunday for their first of 12 back-to-back games this season. The Coyotes eliminated the Blackhawks in the first round of the playoffs last season.
