Silfverberg suffered the injury when he was slashed midway through the third period against the Ottawa Senators. He immediately left the game and did not return. Acquired as part of the Bobby Ryan trade with Ottawa this past summer, Silfverberg was enjoying a nice start to the season before the injury. His seven points were fourth best on the Ducks and only Corey Perry had loosed more shots on net than Silfverberg.
The Ducks are suddenly thin up front. Mathieu Perreault is day-to-day after spraining his left wrist on Friday. The Ducks will get Dustin Penner back on Sunday, fully recovered from a nasty hit from Dallas Stars forward Ryan Garbutt that got Garbutt suspended for five games.
