Lehtera (upper body) is not with St. Louis on the team's current road trip and it is believed he may be dealing with concussion-related issues, the St. Louis Post-Dispatch reports.

EDGE Analysis

Lehtera left Thursday's game after getting hit in the face with a puck, requiring stitches, but this is the first we're hearing about a concussion. We expect more news in the coming days. With Lehtera missing the last two games, Ty Rattie has been activated in his place. Going forward, the Blues have two more games on the current trip, Tuesday in Ottawa and next Sunday in Minnesota.
