The Ducks announced a number of injuries and illnesses after Friday’s morning skate at the Honda Center. Here’s the list:

Goalie Frederik Andersen suffered a concussion during a relief appearance during an 8-3 victory Wednesday against the Calgary Flames. He was unavailable to play in Friday’s game against the Vancouver Canucks. His layoff is to be determined, but the Ducks recalled Anton Khudobin from San Diego of the AHL.

Left wing David Perron has a separated right shoulder and will be lost to the team for between four to six weeks, an MRI revealed. Perron was hurt during the Ducks’ victory March 20 over the Winnipeg Jets. Perron sat out for the sixth game Friday. He has been able to work out in the gym, but hasn’t resumed skating yet.

Center Rickard Rakell underwent an appendectomy and will be sidelined for up to one week. Chris Wagner was recalled from San Diego to fill his spot. Rakell fell ill and couldn’t play Wednesday. It was later determined that he needed an appendectomy. Ryan Getzlaf had a similar procedure earlier this season.

Defenseman Hampus Lindholm was sent home before the morning skate Friday because he was ill.

The Ducks also were without defensemen Kevin Bieksa and Simon Despres because of upper-body injuries.
