SHANGHAI - Yao Ming should make it official on Wednesday, announcing what is widely expected to be his retirement from the NBA and a sport that made him a household name in China.

The 7-foot-6 (2.29-meter) center for the Houston Rockets played for eight seasons in the NBA, but has missed 250 regular-season games over the past six years. His career, including frequent appearances for the Chinese national team at Olympics and world championships, has been punctuated by leg and foot injuries.

On Wednesday, a large reception hall at a hotel in the Pudong section of Shanghai - Yao's hometown - has been booked for what will likely be the country's media event of the year.
