Efes Pilsen of Istanbul, Turkey has de-registered two players from its Euroleague roster and released both following their refusal to travel with the team to Top 16, Game 3 in Belgrade, Serbia a week ago. Efes on Wednesday officially de-registered the team's top scorer, shooting guard Drew Nicholas, and backup playmaker Rashad Wright. A third player, center Loren Woods, is expected to follow suit shortly. A fourth who also skipped the game in Belgrade, power forward Andre Hutson, was reinstated by the team over the weekend. All four players cited personal security concerns last week for not traveling to Serbia after communication they received from the United States embassy there contradicted guarantees of security from the Turkish embassy in Belgrade as well as city authorities and the host club, Partizan Belgrade. Three other United States citizens with Efes, guard Scoonie Penn, forward Kenny Gregory and head coach David Blatt, made the trip and participated in the game, which was held without incident. Nicholas has averaged 16.5 points and 2.9 assists in 14 Euroleague Basketball games this season. Wright had an average score of 3.2 points in nine Euroleague games. Meanwhile, Woods had averages of 8 points, 6.5 rebounds and 1.4 blocks in 16 Euroleague games.
