Every NFL season begins with optimism, yet September often reveals far more than preseason expectations. The opening weeks of 2026 feature championship contenders, major offseason storylines and historic international matchups with significant early playoff implications.
Each featured matchup offers more than entertainment. Early results provide valuable insight into which franchises are ready to meet expectations, which offseason decisions are paying off and where the biggest questions still remain across the league as the season begins.
1. New England Patriots at Seattle Seahawks
The 2026 season begins on September 9 at Lumen Field in Seattle, where the defending Super Bowl champion Seahawks welcome the Patriots for a highly anticipated Kickoff Game. Once the banner ceremony ends, both teams face immediate pressure to deliver.
Seattle must prove last season’s championship was the start of something bigger rather than the peak of its current roster. Opening-night distractions have caught defending champions before, making an early statement almost as important as the victory itself.
New England arrives with different motivations. Drake Maye continues establishing himself among the league’s brightest young quarterbacks, and a win in one of football’s toughest road environments would reinforce the Patriots’ Super Bowl credentials.
Before kickoff, many fans also use NFL matchup odds to compare game lines and futures while following training camp developments and preseason storylines. Together, those insights add another layer of context to an opening game that already feels like playoff football.
2. Green Bay Packers at New York Jets
MetLife Stadium in East Rutherford hosts one of September’s biggest tests on September 20, when Green Bay faces a Jets defense rebuilt to slow elite passing attacks. This matchup will quickly show whether those changes have worked.
Green Bay presents the perfect challenge. The Packers’ balanced offense combines an aggressive passing game with creative play design, forcing opposing defenses to communicate from the opening drive. Any hesitation or breakdown could quickly prove costly.
New York, meanwhile, enters the season determined to change the conversation surrounding the franchise. A strong performance against one of the NFC’s top offenses would validate the front office’s aggressive offseason while giving supporters genuine optimism.
September rarely defines a season on its own, yet games like this often establish the confidence and momentum that successful teams carry into October and beyond. They can also shape perceptions long before playoff races begin.
3. San Francisco 49ers vs. Los Angeles Rams
The Melbourne Cricket Ground becomes the center of the football world on September 11 as the 49ers and Rams carry one of the NFL’s fiercest rivalries to Australia. Few divisional matchups could better showcase the league’s growing international ambitions.
Both organizations enter 2026 with legitimate playoff expectations, making this far more than a promotional event overseas. A divisional victory earned this early could become an important tiebreaker later in the season, particularly in a highly competitive NFC West.
Preparation extends beyond football. Coaches, sports scientists and performance staff all help players adjust to long-distance travel, unfamiliar routines and time-zone differences. The team that handles those details best could gain an important advantage before kickoff.
Melbourne provides an unforgettable setting, but the intensity between these rivals should remain exactly the same. Familiar opponents meeting in unfamiliar surroundings on the international stage creates one of September’s most fascinating contests.
4. Baltimore Ravens vs. Dallas Cowboys
Maracanã Stadium in Rio de Janeiro hosts another landmark international matchup on September 27, where the Ravens and Cowboys bring two of the NFL’s biggest brands to one of world sport’s most iconic venues before a global audience.
Baltimore’s physical identity consistently challenges opponents, while Dallas continues searching for the consistency to turn championship expectations into postseason success. Both teams expect to contend, making every early-season game important.
Cross-conference games rarely attract the same attention as divisional clashes, yet this contest remains significant. Victories over fellow contenders build confidence, while defeats often raise questions that linger into the opening weeks of the season.
The Brazilian setting only adds to the spectacle. With passionate supporters expected from both sides, Rio becomes another reminder that the NFL’s biggest games increasingly extend far beyond North America. That reach continues expanding the league’s global profile.
5. Kansas City Chiefs at Miami Dolphins
Hard Rock Stadium in Miami Gardens welcomes one of September’s biggest AFC showdowns on September 27, as Patrick Mahomes and the Chiefs travel south to face the Dolphins in a game with enormous conference implications between AFC contenders.
Few teams understand the importance of early tiebreakers better than these organizations. Both expect to challenge for the AFC’s top seed, making a September victory potentially valuable later in the season when postseason positions are eventually decided.
Conditions also shape the contest. South Florida’s late-September heat and humidity demand careful player rotation, disciplined game management and strong conditioning. Visiting teams often find the fourth quarter as challenging as containing Miami’s explosive offense.
Elite quarterbacks, innovative coaching and genuine Super Bowl ambitions combine to make this one of the strongest matchups anywhere on the September schedule. Both teams expect to contend deep into January, making every early result meaningful.
