Johnson will not play in Monday's game against the Celtics after having surgery on his mouth, Anthony Chiang of the Palm Beach Post reports.
It appears as though it was a teeth issue for Johnson that will hold him out and he doesn't currently have a timetable for his return. Nevertheless, with Dion Waiters (groin) also out Monday, the Heat will be light on backcourt depth and allow for Josh Richardson to potentially play a heavy dose of minutes at both point and shooting guard.
