The Japanese Skating Federation announced Tuesday that Daisuke Takahashi has withdrawn from the Cup of China, to take place in Beijing later this week. The 22-year-old skater suffered a right knee injury in practice last Friday. He will undergo tests to determine the extent of this injury and whether he will be able to compete at his second Grand Prix event, the NHK Trophy, which begins in Tokyo on Nov. 27. Takahashi won a world silver medal in 2007 and placed fourth in 2008. He was considered the favorite to win the Cup of China. In his absence, European champion Tomas Verner of the Czech Republic and American Stephen Carriere, who won the world junior title in 2007, are expected to contend for top honors.
