China's already slim chances in men's basketball just took a serious blow when star forward Yi Jianlian went down with a knee injury.

Yi appeared to twist his right knee late in a loss to Australia on Thursday.

Yi had to be helped off the floor by teammates and he was still limping badly when the game was over.

Chinese coach Bob Donewald says it's too soon to tell how serious the injury is. Yi will be examined by doctors later in the afternoon.

Yi, an NBA player, played most recently for the Dallas Mavericks.
