Neither Yoo nor Tan has played together internationally since the Vietnam Open, when they retired after one game. Yoo played in a domestic tournament about a month after that. Not sure about Tan so it's unclear which one of them might have been injured. Yoo's next tournament is the Dubai Int'l Challenge, where he will be there along with the members of 4 Korean 'pro' teams, which all represent cities: Suwon (Yoo's team) and Dangjin are sending men's teams, and Pocheon and Hwasun are sending women's teams. Tan's next tournament is the Macau Open, where he will be playing with Kim Sa Rang.
