The 7-foot-6 center for the Houston Rockets played eight seasons in the NBA, but has missed 250 regular-season games over the past six years.

Reports have been circulating for nearly two weeks that the 30-year-old star would retire, but the Rockets have not commented due to the NBA lockout and his management refused to confirm the reports. The NBA said it has not received official retirement paperwork from Yao.

An eight-time All-Star selection, Yao averaged 19 points and 9.2 rebounds in his eight seasons, but his impact on the league goes far beyond the numbers.

Yao single-handedly expanded the NBA's reach throughout Asia, spiking merchandise sales and TV ratings for games after the Rockets made him the top overall pick in the 2002 draft.
