Jonathan Toews was placed in concussion protocol Friday by the Blackhawks and there is no timetable for his return.
"Obviously he's a huge part of this organization and we're going to miss him," Chicago coach Derek King said. "… but we're making sure we do the right thing by this. There's no time frame, it's when he's feeling right. You can't mess around with this stuff. We'll just go day by day every day and see how he's feeling. When he's ready, he'll come back and join us."
The forward had an assist in an 8-5 win against the Detroit Red Wings on Wednesday and scored 19 points (four goals, 15 assists) in 43 games this season.
The Blackhawks captain missed his first game of the season Friday when Chicago lost 6-4 to the Colorado Avalanche.
"He's a voice in the room and he's a presence in the room and on the ice for us," Chicago defenseman Seth Jones said. "He plays in all situations and our best face-off guy, takes the most important face-offs, 5-on-5, in our [defensive] zone and on the penalty kill. So we're going to lose a big part of that. So we'll have to have guys definitely fill in and have a next-man-up mentality until he gets back." -- Tracey Myers
