Brown was put on the exempt list Friday after newly documents released last week by the King County (Wash.) Sheriff's Office showed he admitted to years of physical, verbal and emotional abuse against his then-wife Molly Brown.
The kicker had three days to appeal the league decision, but a league source told ESPN's Adam Schefter on Monday that Brown is not expected to appeal. Players are added to the exempt list by Commissioner Roger Goodell, effectively removing them from team rosters and making them ineligible for play. Goodell alone has the authority to revoke this status.
NFL senior vice president Adolpho Birch sent a letter to Brown on Friday stating the league wanted to investigate further upon learning of the new documents that stem from Brown's 2015 arrest.
The new information prompted the Giants to announce Thursday that the Brown would not travel with the team for Sunday's game in London against the Los Angeles Rams. The 37-year-old veteran may be done playing for the Giants.
The NFL suspended the kicker for only one game for the May 2015 incident -- Brown was arrested for allegedly grabbing the wrist of his then-wife in a heated dispute at a home the couple shared in Woodinville, Wash. -- because of "insufficient information to corroborate prior allegations."
The Giants then signed Brown to a two-year, $4 million extension this offseason. By being placed on the commissioner's exempt list, Brown will still be able to collect his base salary of approximately $1.15 million.
The new documents were part of the final case file at the King County Sheriff's Office for Brown, who was charged with assault in the fourth degree/domestic violence after an incident with his ex-wife.
Brown's ex-wife told police that he had been physically violent with her on more than 20 instances over the past several years.
