He injured the knee in March during a game against the Los Angeles Lakers, and hasn't played since. Rubio spoke with reporters at the Target Center for a few minutes on Thursday, (via the Star-Tribune):
"I don't know, they say December, but it could be January," he said. "I don't want to say a time because I don't want to rush it. I want to be ready when I am ready."
"There's not a time because it depends on how the knee goes," he said. "Now I start running and I feel good. In three, four weeks, I'm gonna start agility and if my knee swells a little bit, I have to stop. If not, I'm going to keep pushing it. I'm trying to do as much as I can do. They have to stop me sometimes because I want to do more. Sometimes it's just bad for my knee to do more things."
Rubio will be with the Timberwolves when they begin their training camp on Tuesday, but he will be a limited participant in the practices. At the moment he is limited to just running and shooting free throws; he can't move laterally at this point in his recovery.
The Timberwolves will get their training camp under way on Tuesday, Oct. 2, from Mankato.
