ANAHEIM -- Anaheim Ducks forward David Perron will be out four to six weeks with a separated right shoulder, and goalie Frederik Andersen is out indefinitely with a concussion.
The Ducks announced a surge of injury woes Friday before their game against Vancouver, potentially imperiling their run for a fourth consecutive Pacific Division title in the regular season's final days.
Rickard Rakell also is out for a week with appendicitis, and defenseman Hampus Lindholm will miss at least one game with an illness.
Perron has been outstanding since arriving in a midseason trade with Pittsburgh, getting eight goals and 12 assists in 28 games.
