The duo will miss tomorrow's visit of Reading and the last game of the season against Derby at Pride Park.
Brunt has a slight knee strain while Adams, impressive of late, has hurt his groin - Folly should start after recovering from concussion.
Paul Sturrock will not risk the likes of Tommy Spurr and Sean McAllister in the game though as he thinks playing against the champions could prove to be difficult for the youngsters.
Sturrock is also set to keep Leon Best up front but he could give opportunities to the likes of Drissa Diallo, Richie Partridge, Steve MacLean and JP McGovern back into contention.
The club have also issued a statement to supporters telling them to keep off the pitch at the end of the game so the squad can thank the fans for their support this season.
