New Orleans replaced Crabtree on the active roster with linebacker Todd Davis, who had been on the practice squad.
Graham leads the Saints with 34 catches for 376 yards and three touchdowns. He returned to practice on a limited basis Thursday and Friday. He was listed as questionable for Sunday's game in Detroit.
The Saints had a bye last week.
