The 2019 NBA Draft is just one week away, and presumptive No. 1 overall pick Zion Williamson is suing to end what he and his representation are alleging as an “unlawful” agreement with a Florida marketing company.

Shortly after he declared for the draft, Williamson signed a marketing deal with a group called Prime Sports and agent Gina Ford. The agreement in place had suggested that termination was impossible for five years after it had been signed.

Detailed in a story by ESPN Insider Adrian Wojnarowski, however, Williamson is suing because Prime Sports are not affiliated with the National Basketball Players Association:

According to the suit, the agreement was unlawful under North Carolina's Uniform Athlete Agents Act because Prime Sports is not certified by the National Basketball Players Association or a registered athlete agent in North Carolina or Florida. Additionally, the agreement failed to contain, as required under the UAAA, a conspicuous notice in boldface type in capital letters informing the athlete that by signing the agreement he was losing his eligibility to compete as a student-athlete.

Williamson signed an agreement to join Creative Artists Agency on May 30, and informed Prime Sports the next day that he would be terminating the agreement.

Prime Sports has suggested that they would sue in excess of $100 million for broaching the terms of the deal, but Jeffrey S. Klein–an attorney for Williamson–said that the contract was a clear violation of North Carolina's Uniform Athlete Agents Act.

Williamson is hardly a stranger to this kind of controversy. In April, Duke University looked into claims that Nike had paid Williamson's mother.

The suit will hardly impact Williamson's status as the top pick, though he would likely prefer a smoother transition into the NBA.
