Gallinari only played sparingly in a win over Charlotte on Saturday. He's averaging 16.9 points this season.
Nuggets coach George Karl was fully expecting Gallinari to be in the starting lineup, saying before the game, "I think he's good. I didn't even check today. He told me this morning it was fine."
Earlier this month, the smooth-shooting Gallinari missed two games with a sinus infection. He is Denver's top threat from 3-point range.
