Tom Brady is about to complete his second decade as a New England Patriot, and just upped his pay by $8 million. He did it, though, without tying himself to the franchise beyond the upcoming season.

His contract is a two-year extension through 2021, but the latter two years are void, per ESPN. They’ll have to negotiate again before the end of this year, should Brady want to return. According to NFL Network’s Ian Rapoport, the contract includes a clause preventing Brady from being franchise tagged.

“It’s a unique situation I’m in,” Brady told reporters Monday. “Twentieth year with the same team, I’ll be 42 years old. So pretty much uncharted territory for everybody. I’m going to go out there and do the best I can this year and see what happens.”

Brady, who will reportedly make $23 million this year, hasn’t slowed down yet. His trainer, Alex Guerrero, has said he thinks Brady can play until age 50.

“I don’t want anyone to think I’m different from anyone else,” Brady said. “Football is a tough business. It’s a production business. I’m ready to go this year, and that’s what matters and that’s where my focus is.

“I’ve just had a great history here. I love playing quarterback here. I love this team, this organization, Mr. (Robert) Kraft, Jonathan (Kraft), coach (Bill) Belichick, all the coaches, all the players. The focus is this year and what we have to do. That’s where I’m focused. That’s all that really matters in the end, and that’s what this team expects of me — to put everything into it, like I always have. I’m really excited for this year.”
