Striker Jan Koller, sidelined since September with a knee injury, could be ready to play in the Czech Republic's World Cup opener against the United States on June 12.
Czech coach Karen Bruckner said Thursday that the Dortmund striker may still play in a Bundesliga game this season.

"He's optimistic about his participation at the World Cup," Bruckner said.

Koller was expected to be sidelined for at least eight months after tearing ligaments in his left knee during a Bundesliga match in September.

Koller's recovery is good news for Bruckner, who would have a problem replacing the 6-foot-7 (2.0 meter) striker.

"There's no other Koller," Bruckner said.

Koller has 40 goals in 66 internationals games, and nine goals in the Czech Republic's 2006 World Cup qualifying campaign.

Bruckner said three other players were still doubtful for the World Cup: Bordeaux midfielder Vladimir Smicer, Ajax defender Zdenek Grygera and striker Vratislav Lokvenc of Salzburg.

World Cup squads have to be named by May 15.

The Czechs play in Group E along with the United States, Ghana and Italy.
