The AP reports:

The Nuggets will be without forward Danilo Gallinari for a week to 10 days after X-rays revealed that he had fractured his left big toe.

Gallinari stubbed his toe late in a loss to Portland on Friday night and was held out of Monday night’s 100-90 victory over the Atlanta Hawks because of continuing soreness. Soon after beating Atlanta 100-90, the Nuggets announced that the toe was broken.
Gallinari scored 30 points against the Blazers, one shy of tying his career high.
