BEIJING – After receiving U.S. government approval, Iranian center Hamed Ehadadi has been cleared to sign with NBA teams, Yahoo! Sports has learned. The NBA sent out an email to executives late Wednesday afternoon informing its 30 teams they were free to enter into negotiations with the 7-foot-2 Iranian Olympian, as well as one of his teammates on Iran’s national team: guard Mohammadsamad Nik Khahbahrami. Just five days ago, the NBA had informed its general managers that they were forbidden to enter into negotiations with Ehadadi, pending a license from the U.S. Office of Foreign Assets Control. The license was granted and Ehadadi, 23, who averaged 16 points and 10 rebounds for winless Iran in Beijing, is a free agent.
