Very for Yao Ming fans:

As the NBA draft approached, the grim truth about Yao Ming’s(notes) broken left foot hung like an anvil over the Houston Rockets. The fear isn’t that he’s just lost for next season, but longer.

The Rockets and Yao’s reps are frightened over his future, and the concern is the most base of all: Does Yao Ming ever play again?

“The realization has hit them that this is grave,” one NBA general manager said.

For now, the Rockets have privately told league peers it could be a full season before Yao might be able to return to basketball. Multiple league executives, officials close to Yao and two doctors with knowledge of the diagnoses are describing a troubling re-fracture of his navicular bone. Three pins were inserted a year ago, but the foot cracked in the playoffs and isn’t healing.

“It sounds like he’s missing most of next season, if not the entire 82 games,” one league executive who has had recent discussions with the Houston front office told Yahoo! Sports. “That’s all that [the Rockets] will concede quietly, but they know it’s probably much worse.”

Houston general manager Daryl Morey refused comment on Monday and a team spokesman said the Rockets will not have further comment until Yao undergoes additional medical tests.
