Ducks' Corey Perry out 3-4 weeks with knee injury
The NHL-leading Ducks announced the prognosis Tuesday for the 2011 NHL MVP.
Perry leads the Ducks with 14 goals despite missing six games with mumps last month. He has 22 points in 23 games.
A long-term injury is unusual for the durable Perry, who had 43 goals and 39 assists last season. The former 50-goal scorer has missed just 11 games in the previous six seasons combined.
Perry will miss his eighth game this season when Anaheim hosts Edmonton on Wednesday.
