Bournemouth midfielder Hamed Traore will be out for "some time" after contracting malaria, says manager Andoni Iraola.
The 23-year-old Ivory Coast international was treated in hospital after the November international break.
He has not been named in the Ivory Coast squad for the Africa Cup of Nations, which begins on 13 January.
"The past few weeks have been a tough situation for him personally," said Iraola.
"We have to make sure that he is OK and he recovers properly."
Traore is now recovering at home and will have further tests.
A tropical disease spread by mosquitoes, malaria is not contagious.
