Adam Jahns of the Chicago Sun-Times is reporting that the Chicago Blackhawks center and captain, Jonathan Toews, remains day-to-day with what is believed to concussion symptoms. The 23-year-old Toews has missed four straight games, during which the Blackhawks have gone 1-3, but does not appear likely to play Wednesday night either:

"[Toews] is the same," coach Joel Quenneville said after practice at Johnny's IceHouse West on Tuesday. "He didn't skate today. He's about the same he's been the last few days. No progress."

Quenneville also suggested that the Toews' absence has been frustrating to more than the fans at home:

"I think he's watching games and he's disappointed he can't be out there to help us. Injured guys definitely deal with that, especially at this time of the year. Knowing the leader that he is and how meaningful it would be for him to be in our lineup, that's part of the frustration as well."

The Blackhawks play the Toronto Maple Leafs on Wednesday night, hoping to snap their 3-game losing streak.
