The Lod District Court agreed Friday with an appeal by police officials that the athlete should remain in jail, Ynetnews reported.
The court reversed a decision by Magistrate's Court.
A District Court judge said the player, a member of an Israeli soccer team, might flee the country because he is a foreign national.
The suspect was held in the death of 20-year-old Zehava Chakol, whose body was found Wednesday, clothed only in a shirt, outside the hotel in Netanya where the athlete was staying.
An autopsy found the woman died from strangulation.
The player, who was not identified in the report, and a friend were arrested Wednesday. The player told police Chakol had visited them in their apartment but described her only as an acquaintance.
Guy Ben Zvi, the player's attorney, said the lower court had "clearly stated there is no probable cause" when releasing his client Thursday on house arrest.
