After two decades as a New England Patriot, Tom Brady will be wearing a different uniform in 2020.
The six-time Super Bowl winner was drafted by the Patriots in 2000 and has played 326 games for New England in the regular season and playoffs.
Yet Brady has not agreed a new deal with the Patriots, who in turn will not apply the franchise tag to their quarterback, and he confirmed on Tuesday that he will continue his "football journey" elsewhere.
The 42-year-old is not alone in being a great quarterback who switched late in his career, though, and here we take a look at others who wound up moving away from the franchises they became synonymous with.
PEYTON MANNING
The Indianapolis Colts' Lucas Oil Stadium is known as 'The House That Peyton Built', such is Manning's standing in the Hoosier State
Manning, the first overall pick in the 1998 NFL Draft, took the Colts to the playoffs in 11 of his 13 seasons as the starter, but in 2012 Indy cut ties rather than pay an aging quarterback coming off a succession of neck surgeries a $28million bonus.
The Colts also had the first overall pick in the 2012 NFL Draft which they spent on Andrew Luck, then considered the most sure-fire QB prospect since, well, Manning.
But 'The Sheriff' was not done. In four seasons with the Denver Broncos he twice made the Super Bowl, set NFL single-season records for passing yardage (5,477) and touchdowns thrown (55) and added a second ring at Super Bowl 50, after which he headed off into the sunset.
JOE MONTANA
Brady's childhood hero won four Super Bowl rings across 14 seasons with the San Francisco 49ers, though he would end his career as a member of the Kansas City Chiefs.
Montana missed virtually all of 1991 and 1992 with an elbow injury and in 1993, faced with one of the biggest quarterback controversies of all time, the Niners decided to apply their succession plan and stick with reigning MVP Steve Young under center.
So Montana was shipped to Kansas City, where he took the Chiefs to the playoffs in back-to-back seasons before calling it a day.
At the culmination of Montana's final season in 1994, the Niners won their fifth Super Bowl title with Young as the starting signal caller.
BRETT FAVRE
Though Favre was drafted by the Atlanta Falcons, it was in TitleTown where the gunslinger made his name as he racked up the yards and records across 16 seasons and led the Green Bay Packers to victory at Super Bowl XXXI.
Favre appeared content to bow out in March 2008, when Aaron Rodgers had been identified as his heir apparent, yet things got messy when the veteran performed a retirement U-turn in July.
Green Bay had no interest in trading him to the Minnesota Vikings, their rivals in the NFC North, so Favre was moved to the New York Jets, where he spent one up-and-down season before retiring again.
Yet in 2009 Favre did the unthinkable and signed for the Vikings. Minnesota went all the way to the NFC Championship Game - beating the Packers twice in the regular season along the way - but Father Time appeared to have finally caught up with Favre in the 2010 season and on this occasion his retirement stuck.
JOE NAMATH
While his statistics do not measure up to Brady, Manning et al, Hall of Famer Namath is still one of the most renowned NFL quarterbacks of all time.
His "guarantee" that the underdog New York Jets would beat the Baltimore Colts in Super Bowl III is etched into NFL folklore.
Away from the gridiron, 'Broadway Joe' was perhaps the NFL's first celebrity and it seemed fitting that he went from the Big Apple to the City of Stars, signing for the Los Angeles Rams in 1977 after he had gone 4-17 as a starter in the previous two seasons.
However, by that point, injuries had taken their toll and Namath's time in the NFL ended with a four-interception outing against the Chicago Bears on Monday Night Football. At least he was in the right place to launch his acting career...
