Tom Brady has filed his retirement letter with the NFL and National Football League Players Association (NFLPA), effectively rubber-stamping the end of his professional career, according to reports.
The veteran quarterback originally announced his retirement last year following two seasons with the Tampa Bay Buccaneers, before walking back on his decision.
Following Tampa Bay's defeat in the Wild Card round to the Dallas Cowboys last month, however, the 45-year-old announced he was to quit for good.
On Friday, ESPN's Adam Schefter reported that Brady has written to the league and the NFLPA to formally confirm his decision to retire.
The move makes the seven-time Super Bowl winner eligible for the Class of 2028 in the Pro Football Hall of Fame, to which he is likely to be an immediate inductee.
Across a two-decade-plus tenure following his selection by the New England Patriots, Brady became one of the NFL's undisputed greats.
During his time in New England he won six Super Bowls, before adding a seventh ring to his collection during his spell in Florida with the Buccaneers.
Brady is set to take up a role as a broadcaster with Fox Sports for their NFL coverage following his retirement, though he will not start in the role until 2024.
He is due to instead take a year out from the sport, missing the 2023 season in all capacities, before he joins the commentary booth the following year.
J.J. Watt, the former Houston Texans and Arizona Cardinals defensive end who announced his retirement in December, quoted tweeted Schefter's report with the caption: "I was unaware there was paperwork... Definitely not gonna [sic] fill that out, but definitely retired."
