Dunn fell awkwardly after a dunk Wednesday night, landing face first on the United Center floor. Initial test results suggested that Dunn had been cleared of concussion symptoms, but he did fall hard enough to chip and dislocate his two front teeth.
Dunn will not travel with the team when it leaves for a three-game road trip on Friday.
In what’s been widely regarded as a breakout season, Dunn has averaged 13.7 points, 6.4 assists, and 4.6 rebounds per game for the Bulls. Backup point guard Jerian Grant is expected to slide into the starting lineup during Dunn’s absence.
