At least one rival team filed a formal complaint to the NBA league office on Wednesday regarding the Milwaukee Bucks' reported sign-and-trade for Bogdan Bogdanovic, sources tell Eric Fischer of Bleacher Report.
The league informed both the Bucks and Sacramento Kings that afternoon that it would open an investigation into the alleged sign-and-trade already being agreed to between the parties.
Bogdanovic's camp insisted they never discussed the particulars of an agreement with Bucks officials and that they were only made aware of the negotiations. Bogdanovic even let Giannis Antetokounmpo and Thannis Antetokounmpo know he had never agreed to a contract with the Bucks.
The Bucks and Kings agreed to a framework of a sign-and-trade with Donte DiVincenzo, Ersan Ilyasova and D.J. Wilson going to Sacramento in exchange for Bogdanovic and Justin James. The Bucks would have then become free to negotiate a contract with Bogdanovic when free agency opened on Friday.
All the players included within the trade framework were notified.
