Ricky Rubio has cleared the final obstacles standing in his way from joining the Minnesota Timberwolves for the 2011-12 NBA season, according to sources.

Rubio will hold a news conference in Barcelona on Friday to discuss his basketball future.

"Goodnight everyone," Rubio tweeted in Spanish. "Tomorrow morning I give a press conference to say my future. A hug and see you tomorrow."

David Stern must officially give his approval, but a source said, "It's just a formality. It's done."
