If Luol Deng and the Bulls can't come to terms within the next two weeks, he will end talks and tell management that he plans to leave the organization as a free agent next summer, a source close to Deng told Yahoo! Sports.

Deng is determined to come to terms on a long-term contract, but he has set an Aug. 4 deadline to reach an agreement. Once Deng, 23, leaves the country for the European Championship qualifying tournament, he will a sign a one-year qualifying offer for $4.5 million and become an unrestricted free agent next summer.

When reached on Sunday, Deng?s agent, Jason Levien, would only say, ?We continue to talk to the Bulls and remain hopeful that something can be accomplished.?
