The Boston Celtics are trading Kemba Walker and their 2021 first-round pick to the Oklahoma City Thunder for a package that includes Al Horford, sources told ESPN's Adrian Wojnarowski.
Along with Walker and the No. 16 overall pick in 2021, the Celtics are also sending a 2025 second-round pick to the Thunder in exchange for Horford, Moses Brown and a 2023 second-rounder, sources said.
The trade comes after a disappointing season for Walker, who missed the final two games of the Celtics' first-round loss to the Brooklyn Nets with a bone bruise in his left knee.
