Per the Houston Chronicle…

Yao will play no more than 24 minutes per game, Rockets vice president and athletic trainer Keith Jones said. There will be no exceptions. If Yao has played his 24 minutes and the Rockets have the ball and eight seconds on the clock to make up a one-point deficit, Yao will not play those eight seconds.

Yao’s playing time will not average 24 minutes; it will end there. If he plays 22 minutes in one game, he will not play 26 the next. For that matter, if he plays two minutes one game, he will not play 26 the next. When Yao reaches his 24 minutes, he will be through for that game.

The article goes on to suggest that things could change in the playoffs, but the Rockets are bound and determined to get their big man to April fully healthy.

After missing just two games in his first three seasons, Yao has missed 173 of the next 410 games over the following five seasons, or 42% of his team’s games. What good is a franchise center if the guy can’t make it through the season without some sort of season-ending ailment?

That’s why the Rockets are so intent on limiting his workload. They hope that by reducing his minutes throughout the season, it will enable him to be healthy enough in the postseason.
