reports: China national team center Wang Zhizhi has decided to postpone a knee operation until after the Beijing Olympics. The 30-year-old, who experienced pain in his knee this season with Bayi, travelled to the United States after Bayi’s CBA play-off exit and doctors discovered the big man has a bone spur that needs to be removed. Having surgery now would leave the 2.14m Wang needing two to three months of recovery time, causing him to miss the first part of China’s intensive training ahead of the Olympics.
