Karlovic, Ljubicic withdraw at Olympics
BEIJING -- Ivo Karlovic of Croatia withdrew from the Olympics because of a stomach illness Saturday, less than two weeks after his upset of top-ranked Roger Federer at the Cincinnati Masters.
Fellow Croatian Ivan Ljubicic also pulled out of singles due to back trouble. He still plans to play doubles in the tournament, which begins Sunday.
Karlovic, seeded 14th, was replaced in the draw by Yu Xinyuan of China. Tomas Berdych of the Czech Republic becomes the No. 17 seed and takes Karlovic's place in the draw.
Yu will face Berdych in the first round.
Ljubicic was replaced by Devin Mullings of the Bahamas.
Maria Jose Martinez Sanchez of Spain replaced Lindsay Davenport of the United States, who withdrew from singles Friday because of a lingering knee injury.
