LAS VEGAS — Cooper Flagg ’s first NBA Summer League is over after just two games. The Dallas Mavericks shut down the No. 1 overall pick for the remainder of their time in Las Vegas, a person with knowledge of the situation of the decision confirmed Sunday to The Dallas Morning News.

It’s not uncommon nor unexpected for teams to shut down top picks or NBA rotation players who are on summer rosters early.

Jackson (Michigan State) is now under contract through 2029-30, after renegotiating the final year of his current deal and getting a raise to $33 million for the coming season. The extension kicks in in 2026-27, starting with a salary of $46.2 million.
