Jarrett Allen has become the latest Cleveland Cavalier to sign a maximum contract extension since the conclusion of the 2023-24 NBA season.

Allen signed a three-year, $91million extension with the Cavaliers on Wednesday, according to multiple sources.

The deal will guarantee him $131million over the next five years.

Allen joins Donovan Mitchell and Evan Mobley as Cleveland players to ink extensions this off-season, as the franchise has established itself as a legitimate contender in the Eastern Conference.

The 26-year-old Allen averaged a career-best 16.5 points along with 10.5 rebounds in 77 games last season. His shooting percentage of 63.4 ranked fourth in the NBA.

The 22nd overall pick of the 2017 draft by the Nets, Allen spent his first three-plus NBA seasons in Brooklyn before Cleveland acquired him in January 2021.

He was named an All-Star in his first full season with the Cavs in 2021-22, when he averaged 16.1 points and a career-high 10.8 rebounds.

In 252 games in a Cavs uniform, Allen has averaged 15.1 points, 10.3 boards and 2 assists while shooting 64.2 per cent.

The Cavs reached last season's East semi-finals before being ousted by the eventual champion Boston Celtics with Allen sitting out the entire play-off series due to a rib injury and Mitchell missing the final two games because of a left calf strain.

In the four post-season games he played before his injury, Allen averaged 17 points on 67.6 per cent shooting and 13.8 rebounds.
