Blues center Patrik Berglund is expected to be out until December after having surgery to repair a dislocated left shoulder.
The Blues said Berglund was injured during an offseason conditioning program in Sweden and flew to St. Louis for Tuesday's procedure. The team called it a successful surgery.
Berglund scored a career-high 23 goals and finished with 34 points in 2016-17, adding four assists in 11 playoff games.
