Krug (upper body) left during pre-game warmups and is not expected to play Monday against Anaheim, Lou Korac of NHL.com reports.

EDGE Analysis

Just as Colton Parayko is set to return from a three-game absence, it appears the Blues will be down another top blueliner for at least one game. Krug has four goals and eight points while averaging 19:39 of ice time through 17 games on the year. An update on his status should be available before Wednesday's game in Buffalo.
