Ukraine expect all of the players who were struck down by a mystery stomach bug to be fit to face Sweden on Monday, after they trained again yesterday.
The illness swept through the squad and almost led to the cancellation of Tuesday's 2-0 friendly defeat by Turkey.
Ukraine's team doctor, Leonid Myronov, said the illness first occurred on Monday afternoon, when the team masseur felt ill.
He added: "At 4am [on Tuesday] Denys Garmash came to me with the same trouble. A bit later Taras Mykhalyk, Andrei Voronin, Artem Milevsky, Andrei Shevchenko and Anatoliy Tymoshchuk all complained of feeling indisposed."
