Coach George Karl said before the game Monday night he intended to play Gallinari and Nene only limited minutes as they return from injuries.
Gallinari, the team's leading scorer, missed 13 games with a left ankle sprain, while Nene sat out 10 due to a strained left calf.
The banged-up Nuggets were without versatile swingman Rudy Fernandez (back) and center Kosta Koufos (left knee).
When Gallinari hobbled off the court on Feb. 6, tests revealed a chip fracture in his left foot. But further examinations showed the fracture wasn't caused by his stumble and may have actually occurred before he joined the NBA in 2008.
The team was 6-7 without Gallinari.
