He will miss at least the next two games as he gets treatment, the team said, meaning he will be sidelined Feb. 15 at the Sacramento Kings and Feb. 16 at Phoenix.
Durant dropped 20 points Saturday night, the night before his injury diagnoses, in his first return to Golden State since leaving the team.
He helped lead the Nets to a dominating 134-117 win over the Warriors.
Durant had just come back from missing three games before playing the Dubs due to COVID-19 protocols.
The Nets say there will be further updates on Durant's injury status as they become available.
