Duke wasn't extended a qualifying offer from the Nets prior to Thursday's deadline and will become an unrestricted free agent, Brian Lewis of the New York Post reports.
Duke had his two-way contract converted into a standard deal back in April, but he never received much of an extended look with Brooklyn. He made 23 appearances at the NBA level in 2022-23 and averaged 3.7 points and 1.3 rebounds in 9.9 minutes per game.
