It’s official now.

Tom Brady announced that he will retire after 22 NFL seasons in a social media post on Tuesday. Word broke Saturday that the quarterback intended to retire, but he said Monday he was still undecided.

As part of an announcement with an Instagram post Tuesday, Brady wrote: “This is difficult for me to write, but here it goes: I am not going to make that competitive commitment anymore. I have loved my NFL career, and now it’s time to focus my time and energy on other things that require my attention.”

Brady, 44, said on his podcast Monday that he was “still going through the process I said I was going through” as reports of his retirement continued without official word.

“I have always believed the sport of football is an “all-in” proposition – if a 100% competitive commitment isn’t there, you won’t succeed and success is what I love so much about our game,” Brady wrote Tuesday. “There is a physical, mental, and emotional challenge EVERY single day that has allowed me to maximize my highest potential. And I have tried my very best these past 22 years. There are no shortcuts to success on the field or in life.”

Brady retires with seven Super Bowl titles with the Patriots and the Buccaneers, where he spent the last two seasons of his career and won his final title last season. He is the NFL’s career leader in numerous passing categories, such as yards passing (84,520) and touchdowns (624). He was the Super Bowl MVP five times and NFL MVP three times. He is also the career wins leaders (243). Brady was named to the Pro Bowl 15 times. He finished with a 243-73 record in the regular season and 35-12 in the playoffs.

In his lengthy statement, Brady thanked members of the Buccaneers organization, including teammates, coach Bruce Arians, general manager Jason Licht, ownership and fans. He did not mention the Patriots or coach Bill Belichick, with whom he won six of his Super Bowls.

One of his Super Bowl victories came against the Falcons when he brought the Patriots back from a 28-3 deficit to win Super Bowl LI in overtime.

“Tom joined us as the greatest football player of all time, and he quickly showed everyone in our organization what that meant,” Buccaneers coach Bruce Arians said in a statement. “He set a standard and helped create a culture that took our team to the mountaintop. It has been an honor to be his head coach for the past two seasons. I wish it didn’t have to end, but few players have the opportunity to leave the game on their own terms. Even fewer can do it while playing at an elite level. Tom is the exception.”
