From rafaelnadal.com:
Rafa Nadal underwent further medical tests today in Barcelona. He is slowly recovering from his injury and will resume practice next Monday July 20th. He will back in action in Montreal where he is defending champion.
Rafa travelled to Barcelona yesterday and underwent medical exams to see the evolution of the insertion tendinitis of both Quadricipitals Tendons through an MRI and radiography under the supervision of his doctor Angel Ruiz-Cotorro.
Also, Benito? Stop using google as translator, because "evolution of injury" makes people think of bad, bad things. Like the injury has evolved into a more advanced injury, and that is never good in the world of fandom. The word you're looking for is "development". I'm always available to be a translator for your time. I will not require payment, only time alone with Rafa 15 minutes every day. I don't think that's too much to ask.
Please don't think I am ungracious for the update. I am very grateful that you're involving us almost every step of the way. The announcement just didn't need that much sense of occasion.
Maybe I need to chug that vintage after all.
