Brady reached the 1,000-yard plateau during Sunday's win against the Minnesota Vikings. He picked up five yards on two carries after entering the matchup with 995 rushing yards.
"What's up? 9-3. But you know what, the only reason I've been playing 19 years is to get to that 1,000 yards," Brady said in an Instagram video, while walking to his car in the driveway. "And I did it. So, that's it."
"I'm out. Time to ride off into the sunset. Nah, gotta get back to work."
Brady jumped into his Aston Martin during the short video.
Brady also posted a photo of himself wearing a new shirt, which featured his TB12 logo with an addition of a "1K."
"I got mine," Brady wrote. "Finally got to wear it after 19 years."
Brady had a chance to fall back below the 1,000-yard barrier late in Sunday's win when the Patriots were kneeling the ball. Instead of falling back behind the line of scrimmage, Brady moved up so he didn't lose any yards.
"I'm not trying to go backwards," Brady told reporters. "So, I don't want us to go backwards anymore -- try to inch up on those kneel-downs a little bit."
The five-time Super Bowl champion and three-time NFL MVP is completing 65.9 percent of his throws and has 3,342 yards, 20 scores and eight interceptions in 12 starts this season. Brady is averaging 1.7 yards per carry on the ground during his decorated tenure.
The Patriots face the Miami Dolphins at 1 p.m. on Sunday at Hard Rock Stadium in Miami.
