He announced the news on Twitter.
Check out the video where Brady said what he had to say:
It was a difficult last season in the NFL for the greatest player of all time. The Bucs went 8-9 this season but got smashed by the Cowboys 31-14 in the Wild Card Round of the NFC playoffs. Brady set an NFL record for completions (490) and passing attempts (733) in 2022, though the Bucs finished 25th in the league in points and 15th in yards.
The greatest of all time, for the second time in two offseasons but this time for good, steps away. My understanding is family considerations played a major role in this decision. Tom Brady wanted to play until 45.
And now retires. -Ian Rappoport
