NBA fans will reportedly have to wait until the preseason to see Cooper Flagg in game action again. After the Dallas Mavericks rookie was dominant during Saturday's 76-69 loss to the San Antonio Spurs in Summer League, NBA insider Marc Stein (16:25 mark) reported he will not play again in Las Vegas.

Cooper Flagg's summer league days are over, according to Marc Stein. The Mavericks are expected to shut down the No. 1 overall pick for the remainder of the Las Vegas Summer League, which means the next time we'll see him in game action will be during the preseason.
