Bey sustained a hyperextended left knee in Sunday's game against the Pelicans and won't return.
Bey exited early in the fourth quarter in obvious pain, so his status will be worth keeping a close eye on over the next couple of days as Atlanta heads into a three-game week that begins Wednesday in Portland. Before exiting with the injury, Bey started and played 27 minutes, finishing with 14 points (3-11 FG, 3-8 3Pt, 5-6 FT), five rebounds and two assists.
