Bergendahl's German club Stuttgart announces that the Swedish center six has injured his knee after a collision with Samuel Röthlisberger.
Bergendahl is expected to be out for six to eight weeks.
Jim Gottfridsson suffered a muscle injury last week.
However, he told SVT Sport that the WC would hopefully not be a problem.
"Luckily out of bad luck, I feel.
Time hard to say with a muscle injury.
Braces and waist belt.
But hopefully the WC will not be a problem," wrote Gottfridsson.
The Handball World Cup in Poland and Sweden will be played 11–29 January 2023.
