Zion Williamson is suing to enforce his termination of an agreement he signed with a marketing company based in Florida.

Williamson signed a marketing deal with Gina Ford and Prime Sports on April 20.

That agreement included a clause that it could not be terminated for five years. Williamson's family told Ford and Prime Sports on May 31 that it was ending the agreement. The agency responded by saying that if Williamson terminated the deal, they would sue for damages in excess of $100 million.

Williamson has since signed with CAA Sports for his contractual and marketing representation.

Jeffrey S. Klein, an attorney for Williamson, told ESPN in a statement: "Prime Sports Marketing's actions towards Mr. Williamson blatantly violated the North Carolina statute specifically designed to protect student athletes. 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."

Mike Krzyzewski's grandson Michael Savarino will join Duke as a walk-on for the 2019-20 season.

"He's earned it. Michael was a really good player at Durham Academy, well-coached there, they had their best season ever. Played on a talented team this year. Michael is a leader, he's a good shooter, player," Krzyzewski said last week. 

Savarino appeared in a Sportscenter commercial in 2015 in which he texts Justise Winslow an emoji on behalf of Krzyzewski.
