Tom Brady, one of the greatest players in the history of the NFL, is coming back for his 23rd season just a month after announcing his retirement.
But Brady has now said he has "unfinished business" and will rejoin the Tampa Bay Buccaneers.
"These past two months I've realised my place is still on the field and not in the stands," he said on social media.
"That time will come. But it's not now. I love my team-mates, and I love my supportive family. They make it all possible."
After being selected by the New England Patriots with the 199th pick of the 2000 draft, Brady led the franchise to six Super Bowl wins.
He left for the Bucs in 2020 and helped them win the Super Bowl in his first season, being named the game's Most Valuable Player for a fifth time.
A three-time NFL season MVP, he led Tampa Bay back to the play-offs last season and still had a year remaining on his contract with the Bucs when he announced his retirement.
