Ludwig Augustinsson, left back, will not be present at the national team's first training session in Malmö on Sunday. The reason is that his family is expecting an addition.
It is unclear when the Anderlecht player will join the gathering.
Under the new national team coach Jon Dahl Tomasson's first matches in March against Portugal and Albania, Augustinsson started in the backline.
Several selected players were absent on Sunday and will join later. The central defender Isak Hien and his defensive colleague Emil Holm from Atalanta will play on Sunday against Fiorentina in an postponed match in the Italian Serie A.
USA player Emil Forsberg and Japan player Samuel Gustafson are on the move. The duo Samuel Dahl (Djurgården) and goalkeeper Kristoffer Nordfeldt (AIK) have matches in Allsvenskan on Sunday. AIK player Anton Salétros is suspended in Allsvenskan and will be present in Malmö.
Sweden will face Denmark in Copenhagen on Wednesday and Serbia at Friends Arena on Saturday.
