A veteran leaves after a late return
Powell rejoined Dallas shortly before training camp, leaving open the possibility of a 13th season with the Mavericks. He played three of their four preseason games, averaging 1.3 points, two rebounds and 3.7 assists in 12.1 minutes, according to Monday's official release.
His place in franchise history is much larger than that final preseason line. Powell appeared in 763 Dallas games, fifth on the team's all-time list. He ranks sixth in total rebounds and offensive rebounds and 10th in blocks. Across his 12 Mavericks seasons, he averaged 6.5 points and 4.3 rebounds.
Dallas acquired him in December 2014 as part of the Rajon Rondo trade with Boston. AP noted that Rondo left before completing a full season in Dallas, while Powell stayed for the next 11 full seasons. President of basketball operations Masai Ujiri praised Powell's professionalism and contributions beyond the court in the team's farewell.
The rest of the weekend's decisions
Poulakidas left after a productive shooting stretch. He made 45.5 percent of his threes in three preseason appearances and averaged seven points. His 16-point game against New Orleans on Wednesday included four makes on eight three-point attempts. Lundy averaged 5.5 points across four preseason games.
The Mavericks also exercised Cooper Flagg's third-year option Saturday. That secures the 2027-28 season under his rookie-scale deal. Flagg averaged 21 points, 6.7 rebounds and 4.5 assists in 70 starts during his Rookie of the Year season.
Dallas opens Wednesday, October 21, at Houston.
