New England Patriots quarterback Tom Brady agreed to a two-year contract extension through 2019 on Feb. 29, but the value of that deal wasn't known until Thursday morning.

It turns out that Brady will get $41 million over two years, with a massive $28 million signing bonus. ESPN first reported the value of the deal, and FS1's Mike Garafolo has confirmed it.

Tom Brady might be cutting Pats a break here and there but this isn't charity. $28m bonus and $20.5m avg in new money, as @FieldYates said.

Before the extension, Brady had two years left on a contract that would have paid him $9 million in 2016 and $10 million in 2017. His base salary in both 2016 and 2017 is now $1 million, according to Garafolo, but he'll be doing just fine with that $28 million signing bonus. He'll then make $15 million in both 2018 and 2019.

Brady, at age 38 now the oldest non-kicker in the NFL after the retirement of Matt Hasselbeck on Wednesday, is now tied to the Patriots through age 42. He ranks fifth in NFL history in career passing yards, behind Peyton Manning, Brett Favre, Dan Marino and Drew Brees.
