The NHL-leading Ducks announced the prognosis Tuesday for the 2011 NHL MVP.
Perry was injured when Wild defenceman Keith Ballard hit him with a low hip check during the Ducks' 5-4 win at Minnesota last Friday.
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.Suggest a correction
