Flagg (shoulder) is questionable to play Monday against the Heat.
The Mavericks diagnosed Flagg with a mild left shoulder sprain Saturday, and the questionable tag suggests a final call on his availability will be made closer to Monday's 7:30 p.m. ET tipoff. With Naji Marshall (illness) already ruled out, Marcus Sasser and Zaccharie Risacher would be the top candidates to start if Flagg is ruled out for Monday's road game.
