Vesely, a native of the Czech Republic, is waiting to acquire his work visa (that's right, NBA players receive work visas, too). He cannot file to get his work visa until he signs his contract with the Wizards. He cannot sign his contract with the Wizards until the NBA lockout is officially over! Oh the drama!
There is a possibility that Vesely will not be in the states in time for training camp. He could still be in his homeland waiting for his work visa (still sounds funny) to be processed.
