Antonsson suffered the injury playing for club side FC Copenhagen in their derby with Brondby.
"The x-ray on Monday morning showed a little break in a bone in the hand. I'll go to Malmo on Tuesday to try out a special protector - with that, I should be able to train as normal and be available to play," Antonsson told the Swedish FA's website.
Sweden coach Erik Hamren is already missing first-choice centre backs Olof Mellberg (suspended) and Daniel Majstorovic (injured),
Sweden, who failed to qualify for the 2010 World Cup in South Africa, are third in Group E on six points, behind the Netherlands (12) and Hungary (9), with the Swedes having a game less played.
