Toews wasn't expected to join the team for their trip. He may have been suffering from concussion symptoms before getting in a car accident on Thursday.

The status of Hjalmarsson (concussion symptoms) is disconcerting. He returned to the Hawks lineup Thursday after missing seven games in a row. He played 16:06 against the Dallas Stars and was paired with defenseman Sami Lepisto for most of the game. Coach Joel Quenneville said Hjalmarsson "was fine, steady" afterward.

Hjalmarsson initially missed practice Feb. 8 in Colorado with the flu while the Hawks were on their nine-game road trip. He said he later felt nauseated in San Jose. When his symptoms didn't go away, he returned to Chicago. He then went on to miss seven games.

"It's just a matter of I want to feel 100 percent when I get back," Hjalmarsson said after rejoining the Hawks on the ice for the first time earlier this week.

Quenneville said Thursday there was "no change" regarding the status of defenseman Steve Montador (upper body). Montador left the game against the Avalanche during their long road trip and hasn't played since.

"It would be nice to give you a timeline on it, but we don't have the precise look or forecast where he's going to be with the injury and the process," Quenneville said. "He's starting to feel better as well. Hopefully, it's not too long."
