The Celtics will send Kemba Walker and a pair of draft picks to the Thunder in exchange for Al Horford, Moses Brown and a future pick, tweets Adrian Wojnarowski of ESPN.

The second-round pick the Thunder will receive in 2025 will be the most favorable between the Celtics and Grizzlies, Mussatto tweets. The second-rounder that Boston will get in 2023 will be the least favorable of the three that OKC owns.

Boston agreed to give Brown a $500K guarantee for next season to make the deal work, according to Marks (Twitter link). The Celtics also generated a $6.9MM trade exception.

The trade is now official, according to a statement from the Thunder, tweets Joe Mussatto of The Oklahoman.
