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.

The #Mavs are shutting down Cooper Flagg for the remainder of Summer League, a person’s familiar with the decision confirms. Flagg averaged 20.5 points, 5 rebounds, 2.5 assists, 1.5 steals and 1 block in his two games against the #Lakers and #Spurs. @TheSteinLine was first.

The Dallas Mavericks have seen enough of Cooper Flagg ... and they must have liked what they saw, as they have shut down the No. 1 pick after two impressive Summer League games.
