Fab Melo suffered a concussion last week walking into a door frame.
Melo had 14 points, 6 rebounds, and 2 blocked shots in Friday's game and 13 points, 10 rebounds, and 5 blocks the next night.
"What did you have, 'Manny being Manny'?" said Doc Rivers. "In five years, when Fab's playing terrific for us here, we're going to have some 'Fab being Fab' moments. It just took kind of a head start."
The Celtics recalled Melo from the D-League to receive treatment for the concussion.
