Ducks center Ryan Getzlaf had a successful non-emergency appendectomy Wednesday, a team spokesman said. Getzlaf’s recovery time is still expected to be four to 12 days, which means he could miss as many as six games. He didn’t play in the Ducks’ 4-3 loss Tuesday to the Dallas Stars after returning to Orange County to have the procedure. He has been feeling pain associated with appendicitis for the last six weeks, the team said Tuesday. He has one assist in eight games this season.
