Iguodala suffered the injury -- officially called a right cervical strain -- on Sunday against Boston.
Without Iguodala, the Nuggets will likely look to start Corey Brewer in his place, as well as the potential for more dual point guard minutes between Ty Lawson and Andre Miller. No Gallinari would typically mean a start for Wilson Chandler, but he's a late scratch with a strained groin. So expect rookie Evan Fournier to likely get a start.
Missing two starters will thin out the normally strong Denver bench considerably, especially when add in one of their top bench performers being out too.
Iguodala, 29, is averaging 13.4 points, 4.7 assists and 5.3 rebounds. Gallinari, 24, is sort of Denver's go-to option, averaging 17.4 points and 5.5 rebounds.
