The Dallas Mavericks have decided that rookie forward Cooper Flagg will not play again in the NBA Summer League, according to reports from veteran journalist Marc Stein. The move comes after the No. 1 overall pick in last month’s draft appeared in just two contests in Las Vegas. Flagg, who starred at Duke before entering the draft, finished his brief stint with a 26-point scoring average, capped by a 31-point performance in a loss to the San Antonio Spurs. No injury has been reported, and the Mavericks have not provided a public explanation for the shutdown, a precaution that has become common for top selections once they log initial professional minutes. With Flagg sidelined, Dallas will evaluate the remainder of its Summer League roster while the 19-year-old turns his focus to preparation for training camp, which begins in early October.
