Probably Yao sustained an injury towards the end of second quarter of the game against the Cavs when he was fighting for a rebound with big Z. He fell down with his hip hitting the floor. This was reported elsewhere. He has played with this injury for 2 games.

He complained it in ShangHai dialect to reporters of ShangHai TV, "Of course i am not happy with the lose, but they (Sonic centers) were not playing basketball. Were that called defense, I could have contain Shark long time ago!" http://sports.sina.com.cn/k/2004-03-03/1130795057.shtml
