Zion suing marketing company for unlawful agreement

Duke star Zion Williamson is suing a Florida marketing company to enforce the termination of an agreement he signed with them shortly after declaring for the NBA draft, his attorneys told ESPN's Adrian Wojnarowski.

However, the 18-year-old's contract with Prime Sports includes a clause that prevents it from being voided for five years and the agency has threatened to sue Williamson for damages in excess of $100 million if the deal is terminated.

Williamson's camp maintains that the agreement was unlawful under North Carolina law because the company is not certified by the National Basketball Players' Association or a registered athlete agent in North Carolina or Florida. In addition, the contract didn't state that Williamson would be ineligible for collegiate basketball by committing to Prime Sports.

"Prime Sports Marketing's actions towards Mr. Williamson blatantly violated the North Carolina statute specifically designed to protect student-athletes," Williamson's attorney told Wojnarowski in a statement. "Mr. Williamson properly exercised his rights under the law to void his business dealings with Prime Sports Marketing. Prime Sports Marketing's continued threats against Mr. Williamson made necessary the filing of this lawsuit."

Williamson has since signed with CAA Sports and is projected to be the No. 1 overall pick in next week's NBA draft.
