The 6-foot-9 Ndour signed with Dallas on July 22 and averaged 4.8 points, 1.5 rebounds and 1.5 steals in 23 minutes per game in four preseason games. He was a target for the final cut Monday after missing the final three exhibition games with a stress reaction in his left leg.
The Mavericks went with experience in the frontcourt over the young Ndour, who averaged 16 points and 8.3 rebounds as a senior last season at Ohio. Dallas kept a third center in JaVale McGee even though the eighth-year player won't be ready for several weeks because of a leg injury.
Dallas opens at Phoenix on Wednesday night.
