Keith will not travel; Shaw goes into concussion protocol

One day after skating with 17 players in a 4-0 loss to St. Louis at the United Center, the injury news did not improve for the Blackhawks.

Coach Jeremy Colliton's team will be without Duncan Keith for at least two more games as the defenseman will not travel on the upcoming road trip to Boston and New Jersey.

Colliton had no further update or timetable on how long Keith will be out with a groin strain he suffered against Colorado on Friday.

Andrew Shaw, meanwhile, became the third Hawks forward to enter the concussion protocol over the last three weeks. Drake Caggiula (out since Nov. 13) and Dylan Strome (out since Nov. 29) both practiced at Fifth Third Arena on Tuesday, but have not been cleared.

If none of the forwards can play at Boston on Thursday, Colliton said "we will solve that problem if we need to," seeming to indicate the Hawks will make a move that allows them to call someone up from Rockford.

Colliton, whose playing career ended due to two concussions, is "keenly aware" that Shaw and Caggiula have both suffered multiple head injuries, and understands their long-term future is much more important than their playing future.

"I care about the guys," Colliton said. "I want them to have the opportunity to play as long as they can. ... Then obviously after they're done I want them to be healthy and enjoy time with their family, all those things."

Slap shots:

Robin Lehner, who missed Monday's game with flu-like symptoms, was at practice Tuesday. The Hawks reassigned Kevin Lankinen to Rockford. ... Alex DeBrincat has not scored in 12 straight games, missing on all 35 of his shots on goal. ... Alex Nylander has a minus-2 rating in four of the last six games. He has just 2 goals and 5 assists in the last 23 games despite playing quite a bit on the top line with Brandon Saad and Jonathan Toews.
