Ivo Karlovic has withdrawn from the French Open with a right foot injury and is doubtful for Croatia's Davis Cup quarterfinal series against Serbia in July.
Karlovic says his Achilles' has been bothering him for months. He told Vecernji list daily on Wednesday that he wants to play at Wimbledon and in the Davis Cup, "but the health is most important." He says he will make a final decision after more medical tests.
Croatia, the 2005 Davis Cup champion, will face Serbia in the Davis Cup quarterfinals on July 11-13.
Mario Ancic, another Croatian player, is struggling with back pains and is also not certain for Davis Cup.
