KIEV, May 23 (Reuters) - Ukraine captain Andriy Shevchenko said doctors would shed more light on his World Cup prospects later this week.
The AC Milan striker's health has been a cause for concern as he has been sidelined with a knee injury since the beginning of the month.
'My health is improving with each passing day,' Shevchenko told a news conference on Tuesday.
'I cannot push my treatment forward too quickly, and nor do I want to. You must not rush these things.'
He said he was returning to Milan on Tuesday -- and a day later 'doctors will examine me and things will become clear on my plans and my hopes for the World Cup'.
But he said he would not be in the line-up for next Sunday's friendly against Costa Rica -- one of a series of warm-ups ahead of the June 9 to July 9 finals in Germany.
Shevchenko is also expected to decide on his future with AC Milan this week. He told the Serie A club that he wants to leave Milan after seven years and has been linked to a move to English champions Chelsea.
Ukraine will play their first Group H match on June 14 against Spain. Saudi Arabia and Tunisia complete their group.
