Tom Brady has announced his retirement "for good".

The seven-time Super Bowl champion announced his retirement in February last year only to reverse that decision 40 days later and continue his career with the Tampa Bay Buccaneers.

Speaking in a video posted on his Twitter account, Brady, 45, said: "Good morning, guys. I'll get to the point right away. I'm retiring for good.

"I know the process was a pretty big deal last time so when I woke up this morning I figured I'd just press record and let you guys know first.

"It won't be long winded. You only get one super emotional retirement essay and I used mine up last year."

Brady won six of his Super Bowl rings during a storied career with the New England Patriots, before adding a seventh with the Buccaneers two years ago.

He leaves with record totals of 89,214 yards and 649 touchdowns in the regular season and 13,400 yards and 88 touchdowns in the play-offs to go with three league MVP awards and five Super Bowl MVPs.

He was named to 15 Pro Bowls, three first- and three second-team All-Pro selections, the league's 100th anniversary all-time team and the all-decade teams for both the 2000s and 2010s.
