Keith Jones told the Houston Chronicle the time limit would be applied strictly and the 7-foot-6 Yao would skip a lot of practice sessions to limit the impact on his left foot.
"Twenty-four is his number all year," Jones said. "Playoffs come, things could change. We're trying to get him through April. We're trying to give him the best chance to play the whole season by limiting stress.
"Even practices, if we play on Monday and play again on Wednesday, can he practice on Tuesday? No. He'll practice, but he won't scrimmage," he said, referring to practice games.
