Keith will not play in the 2017 IIHF World Championships, Brian Hedger of NHL.com reports.
The 33-year-old had another solid year on the blue line, scoring six goals and 53 points over 80 games, and added one assist in Game 3 of the first round. This is the third time in Keith's career that he surpassed the 50-point mark, showing he's not dropping off with age.
Keith is out of the lineup for Tuesday's game against the Avalanche, Tracey Myers of CSN Chicago reports.
It is believed to simply be a rest and not due to any sort of injury. The Blackhawks have the top spot in the Western Conference playoffs sewn up so there is no sense in risking key members of their squad. With Keith and Niklas Hjalmarsson out it is Michal Kempny and Michal Rozsival drawing in.
Keith stretched his point streak to three games with a goal in Thursday's 2-1 win over the Senators.
He has a goal and two assists in those three games and seven points (one goal, eight assists) in his last nine. Keith sits fourth in scoring from the blue line with 48 points.
Keith (leg) left Tuesday's game against the Canadiens briefly due to a leg injury but he was able to return.
Keith was helped off the ice by trainers and was unable to put weight on his leg, but he returned and finished with an assist and a plus-1 while still logging 22:37 of ice time. It appears as if Keith and his fantasy owners have dodged a big bullet.
