Ambri-Piotta will be without their Swedish forward William Hedlund for the first few weeks of the new season.
The newly signed 22-year-old suffered a knee injury in a test game against SC Bern last Friday, which will keep him out of action for a good two months.
The new season begins for the Leventines on Tuesday, September 17, with a home game against the Rapperswil-Jona Lakers.
