Adrian Wojnarowski of ESPN reports the Celtics are trading Kemba Walker, the No. 16 overall pick in the 2021 draft, and a 2025 second-round draft pick to the Thunder in exchange for Al Horford, Moses Brown and a 2023 second-round pick. (Adrian Wojnarowski on Twitter)
The Celtics receive some financial flexibility by moving away from the $73 million owed to Walker. Meanwhile, the Thunder now have three first-round picks in this year's draft.
