The current four-year deal for the package, which allows viewers to see every Sunday afternoon out-of-market game, was set to expire.
DirecTV stock initially spiked almost 2 percent in after-hours trading following the announcement.
"We are pleased to continue our partnership with DirecTV," NFL Commissioner Roger Goodell said in a press release. "DirecTV and NFL Sunday Ticket have served our fans well for 20 years and continue to complement our broadcast television packages. We also appreciate DirecTV's commitment to NFL Network, which it has carried since the channel launched in 2003."
The new deal will expand DirecTV's rights to stream Sunday Ticket programming live on mobile devices and through broadband, the announcement said.
