Koller could be out until quarter-finals

WESTERBURG, Germany, June 13 (Reuters) Czech striker Jan Koller has strained his hamstring and may not be fit until the quarter-final stage of the World Cup, the team's doctor said today.

''It could anything between 10 days and six weeks,'' doctor Jiri Foucek told reporters.

''We hope that he would be able to play in a quarter-final.'' Koller was carried off on a stretcher just before halftime in yesterday's game against the United States, which the Czech Republic won 3-0, thanks in part to an early goal from Koller.

There have been conflicting reports over the severity of the injury, with coach Karel Brueckner saying on Monday it was serious but others, including Koller himself, saying he might only miss a game or two.
