Is Tom Brady retiring? Will Super Bowl be his last game? When does his contract run out?

Tom Brady has appeared in eight Super Bowls. He's won five.

He's four-time Super Bowl MVP, two-time NFL MVP and 13 Pro Bowls. Tom Brady, simply, is the greatest of all time.

But how much longer will New England’s star quarterback continue to give defences and head coaches across the NFL nightmares?

When will Tom Brady retire?

Brady, 40, has a contract for at least the next two seasons. The early indications from within the New England organisation point to him signing a new deal before the start of the 2018 campaign.

That possibility was all-but confirmed when the Patriots traded both of their backup quarterbacks - Jacoby Brissett and Jimmy Garoppolo - during this season.

So how long can Brady go on?

Brady has indicated on multiple occasions his desire to play until he is 45 and while he admitted earlier this week that he would “never want to be a detriment to the team”, there is an obvious and well-documented commitment from him to extend his playing career for as long as possible.

So much so, that he has even made a docu-series about it for Facebook Watch.

‘Tom vs Time’ has been a huge hit with fans and gives a behind-the-scenes look at how Brady prepares for each game.

And in the build-up to Sunday’s Super Bowl, he said: “I've learned and grown in a lot of different ways. My body is very important to me as an athlete.

“Your body is your asset and how well it can handle the rigours of training and playing - that's the length of your career.

“For me, I learned I needed to invest in my body and invest in the things that will help me feel good, or else I would have stopped playing 10 years ago.

“I don't think there's any way you can continue to play if your body can't do it. To me, it's just common sense. It's part of my routine and it's easy for me to do now because I've been doing it for so long.

“I try to eat well, I try to drink a lot of water and hydrate well. I need to have the right amount of rest and have the right mental balance.

“At the end of the day, I don't really think it's that hard because I've learned the things that are right for me and seeing the results just reinforces my own belief system.”

And on whether he’d done enough already to cement his legacy in the NFL, he added: “I don't think about legacy, I've never thought about that.

“I think my motivation comes from trying to be the best I can be for this team. What happened in the past is great but it's not going to win us anything this weekend.”

Doesn't sound like Father Time is going to win this battle anytime soon.
