Faulk's suspension began Saturday. He will be eligible to return to the team Sept. 8, the day after New England's opener against Kansas City.
In July, a judge in Lafayette, La., sentenced the 32-year-old Faulk to a year of probation after he pleaded no contest to misdemeanor marijuana charges. Faulk had been issued a misdemeanor summons for possession of marijuana at a Li'l Wayne concert at the Cajundome in February.
Last season, Faulk had 47 catches for 383 yards and one touchdown. He also had 62 rushes for 265 yards.
