Check out the guy wearing #10 for Germany. He had a pretty big dunk on Yao in the 3rd period. Yao came over to help because #10 beat his guy off the dribble, and Yao ended up getting dunk on. Other than that, and the early fouls Yao looked pretty good. He was not on Dirk except on a few switchoffs.
Looks like he took a bad hit in the stomach from #10. It also looks like he's being quadruple-teamed.
He actually had the ball stripped and every memeber of the German team went for the ball all at once.
