Chychrun (upper body) won't return to Tuesday's game versus the Rangers.
Chychrun was injured early in the first period, and it's enough to keep him off the ice for the rest of the game. The 26-year-old defenseman has earned four points over eight contests while filling a top-four role this season. If he is forced to miss additional time, Alexander Alexeyev could be in line to make his season debut.
