The Dallas Morning News (Brandon George) reports:  Dallas Mavericks’ fans will have to wait a while to see 2008 second-round draft pick Shan Foster knocking down 3-pointers at American Airlines Center. Foster, a 6-6 guard from Vanderbilt, has signed a one-year contract with a team in Europe and will play overseas next season, Mavericks president Donnie Nelson said Thursday in an e-mail. Nelson, who is in China serving as an assistant coach for China’s men’s Olympic basketball team, didn’t specify the team Foster signed with. The Mavericks still retain Foster’s NBA rights.
