Lehtera (head) didn't participate in the Blues' morning skate and is uncertain to play Monday against the Kings, Tom Timmermann of the St. Louis Post-Dispatch reports.

EDGE Analysis

The Blues haven't officially commented on Lehtera's status, but his absence from morning skate seemingly doesn't bode well for his chances of playing later in the evening. Fortunately for the Blues, Paul Stastny (illness) was on the ice for morning skate and appears on track to play, so the team should at least have more options on hand at center if Lehtera is unavailable for a second straight game.
