Brady was drafted by the Patriots in 2000 and has since won five Super Bowl rings, three NFL MVPs and been voted to the Pro Bowl 13 times.
But the legendary quarterback fell at the final hurdle in his quest for a sixth ring last season as the Philadelphia Eagles triumphed in Super Bowl 52.
However, the 40-year-old hinted he could play another five seasons in a social media post that has emerged this week, stating his retirement age could be “cuarenta y cinco” (Spanish for 45).
The comment, from his verified Instagram account, was followed by three emojis representing “speak no evil, hear no evil, see no evil” and came as a reply to a post by ESPN.
The US sports network had posted a picture of Brady accompanied by a quote from an interview with Oprah Winfrey that aired this week.
“I think about it more now than I used to. I think I’m seeing there’s definitely an end coming sooner, rather than later,” Brady had said before adding the “45” comment on social media.
The interview with one of America’s biggest TV stars offered a rare insight into Brady’s future plans, which are the subject of a Tom vs Time, a docs-series looking at his remarkable longevity that premiered in January.
“As long as I’m still loving it,” Brady added.
“As long as I’m loving the training and the preparation and willing to make the commitment.
“But it’s also, I think what I alluded to a lot in the docu-series, there’s other things happening in my life, too.
“I do have kids that I love, and I don’t want to be a dad that’s not there, driving my kids to their games… my kids have brought a great perspective in my life. Kids just want the attention.
“You better be there. And be available to them.”
