"The treatment I’m receiving makes me stop for a long time. If I come back for Davis Cup it would make the injury get worse and I won’t even be at my 50 percent for those matches," Gonzalez wrote on his official website. "I feel really bad about not playing the competition I like the most. I wish things were different but they aren’t.
"If everything turns out as I hope, my return tournament will be at Masters 1000 Toronto."
