Dort won't play in Monday's preseason game against the Grizzlies due to a right knee contusion, Kevin Chouinard of the Hawks' official site reports.
The veteran swingman will be held out of Atlanta's preseason opener, leaving more minutes available for the likes of Corey Kispert, Aaron Wiggins and Jalen Wilson. Dort's next chance to play in the preseason will come Thursday against the Spurs.
