Wolfpack coach Mark Gottfried told Andy Katz of ESPN.com on Monday that Warren "has not decided yet" and will meet with his family Thursday to discuss the matter.
The 6-foot-8 Warren averaged 24.9 points and 7.1 rebounds this season and won ACC Player of the Year honors. He is considered a first-round selection and could wind up being a lottery pick, multiple NBA executives told ESPN.
The news was earlier reported by Yahoo! Sports.
