Nadal unsure of return

"I don't know. I would like to be in Montreal in a week and a half. I will have to push it in the next few days and see," the Spaniard told Spanish state television in an interview conducted at his home in Mallorca.

Nadal has been suffering from tendinitis in both knees aggravated by a gruelling schedule of clay court matches. He has not played a competitive match since losing in the fourth round of the French Open to Robin Soderling on May 31 and did not defend his Wimbledon title.
