Derrick Jones Jr. Petre Thomas-USA TODAY Sports

Free-agent forward Derrick Jones Jr. has reached an agreement with the Mavericks, according to Shams Charania of The Athletic. It’s a one-year deal with a full guarantee, agent Aaron Turner tells Charania.

No other details on the new contract have been released, but Dallas still has $8.4M of its non-taxpayer mid-level exception remaining, along with its $4.5M biannual exception.

Jones, 26, became a free agent when he declined his $3.36M player option with the Bulls in June. He was the last remaining player on the open market who turned down his option for the upcoming season.

Chicago acquired Jones in a three-team trade in 2021 and re-signed him to a two-year, $6.56M contract last summer that included the option. He appeared in 64 games last season, all off the bench, and averaged 5.0 points and 2.4 rebounds in 14 minutes per night.

Jones may find a greater opportunity with the Mavericks, who have revamped their roster this summer with an emphasis on upgrading their defense.

When Jones’ signing becomes official, he will be team’s 15th standard contract. Dallas also has two of its three two-way slots filled, with potential Exhibit 10 contracts looming for Greg Brown, Joe Wieskamp and Jordan Walker.
