BARCELONA, Spain — Rafael Nadal is having his knees checked by doctors and expects to announce his status for Wimbledon in the coming days.

Nadal's Web site says the reigning Wimbledon champion is in Barcelona for medical tests Monday and Tuesday. He is expected to make an announcement by Wednesday.

Nadal withdrew from this week's Wimbledon tuneup at Queen's Club in London, citing knee trouble. His 31-match winning streak at the French Open ended with a fourth-round loss.

Wimbledon starts on June 22.
