Keith is listed as day-to-day, but it's unclear whether he'll play tonight.
Even if it's only for a short time, losing Keith is a big blow for the Hawks.
He is one of the league's top defenseman and logs a ton of ice time, as does fellow defenseman Brian Campbell. Certainly coach Joel Quenneville will be able to juggle the defensive pairs to make up for Keith's absence.
That said, hopefully the concussion symptoms don't linger long and Keith can get back on the ice.
Also, the blow Keith took in the Buffalo game could have been a springboard to victory.
When Ben Eager retaliated (it did look like Stafford got his elbow up a little bit), he racked up six minutes in penalties. The Hawks killed off all six minutes and deflated Buffalo.
Perhaps they can feed off Keith's absence in the same way.
