Sources: Horford returns to Celtics in exchange for Kemba

The Boston Celtics are changing to Kemba walker and their 2021 first-round pick to the Oklahoma City Thunder for a package that includes Al Horfordsources told ESPN’s Adrian Wojnarowski.

Along with Walker and the No. 16 overall pick in 2021, the Celtics will also send a 2025 second-round pick to the Thunder in exchange for Horford, Moses Brown and a 2023 second-round pick, the sources said.

The transaction 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 bruise to a bone in his left knee. After Boston’s elimination, Walker said he needed to focus on regaining his health after dealing with left knee problems for most of 2020 that led to him missing the start of the 2020-21 season. He missed 29 regular season games in total.

The four-time All-Star has two years and more than $ 73 million left on his contract.

Horford will rejoin the Celtics, where he played from 2016 to 2019, participating in the All-Star Game in 2018. He was ruled out in the last 28 games of this season when the Thunder limped to a 22-50 finish.

Horford, 34, has two years and $ 53.5 million left on his contract, with a partial guarantee of $ 14.5 million for 2022-23.

Brown averaged 8.6 points and 8.9 rebounds in his second NBA season after finding a role in Oklahoma City and signing a multi-year contract in March.

The Thunder now have three first-round picks in this year’s draft. Along with the Celtics’ pick, they have the Miami Heat’s No. 18 overall pick and are tied for fourth with the best odds in Tuesday’s draft lottery.
