Deng, who spent a portion of his childhood in Great Britain after leaving Sudan and will play for Great Britain during the 2012 Olympic Games in London, is considering European offers most heavily, according to Rudoy.
"We're not at a point in making a final decision," Rudoy said Thursday.
Deng, who played for Great Britain during the European Championships this summer, is in Sudan, where he has spent time working on his charity endeavors.
Deng averaged 17 points and seven rebounds last season for the Bulls, playing in every game during the regular season and the playoffs.
The Chicago Tribune first reported Deng was considering overseas offers.
