Lehtera's injury that forced him to stay home while the Blues traveled for a West Coast swing has been ruled an upper-body injury, Jeremy Rutherford of the St. Louis Post-Dispatch reports.

EDGE Analysis

Initially, the Blues hadn't indicated the nature of the injury, though it was commonly thought Lehtera suffered the injury after taking a puck to the head last Friday against Anaheim. Regardless of how the Blues want to classify the injury, the fact that Lehtera was left home leaves his availability for the rest of the road trip, which runs through next Tuesday, uncertain. Ivan Barbashev has stepped into the active lineup as a result.
