Perron left Friday's game against Chicago with an upper-body injury and will not return, Jim Thomas of The St. Louis Post-Dispatch reports.

EDGE Analysis

Perron departed in the first period after sustaining a hit from Chicago's Jake McCabe, skating off the ice to the bench on his own before heading to the dressing room. The veteran winger has a history of concussions, and while the exact nature of the injury isn't yet known, there's always concussion concern. Look for an update from the Blues after the game and/or before Saturday's home contest against Columbus.
