Brady confirmed his decision on Wednesday, posting a brief video on social media in an understated fashion, having retired 12 months ago, before reversing that barely 40 days later.
“Good morning guys. I’ll get to the point right away,” Brady said in the video.
“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.
“I won’t be long-winded. You only get one super emotional retirement essay, and I used mine up last year, so really thank you guys so much to every single one of you for supporting me.
“I’m retiring. For good.”
The 45-year-old quarterback, who won titles with the New England Patriots and Tampa Bay Buccaneers, was praised by both franchises.
“His imprint on this organization helped take us to the mountaintop,” Bucs GM Jason Licht said in a statement.
“We will certainly miss him as our quarterback, but I will also miss him as a leader and friend. Our entire organization is indebted to him for what he provided us over the past three years. We won’t ever forget the wins or the accolades and his influence will be felt for years to come.”
Patriots head coach Bill Belichick enjoyed a brilliant partnership with Brady during his time at Gillette Stadium and lauded the three-time NFL MVP.
“Tom Brady was the ultimate winner,” Belichick said in a statement. “He entered the NFL with little to no fanfare and leaves as the most successful player in league history.
“His relentless pursuit of excellence drove him on a daily basis. His work ethic and desire to win were both motivational and inspirational to teammates and coaches alike.
"”Tom was a true professional who carried himself with class and integrity throughout his career. I thank Tom for the positive impact he had on me and on the Patriots and congratulate him on his amazing career.”
