Which NFL teams are still undefeated in 2025?
Watch every NFL game only on DAZN (ex. US, China)
We entered Week 5 with two teams boasting a perfect 4-0 record, but in a league built for parity, perfection is incredibly difficult to sustain. Upsets happen regularly, and even the heavyweights wobble.
After another wild weekend, the roll call of unbeatens got even shorter. So short, it says everything about how fiercely competitive this league really is.
Here's the story behind how the NFL's exclusive club of perfection just took a crazy turn.
Philadelphia Eagles (4-1)
The reigning Super Bowl champions made a strong start to the season, but in Week 5, DAZN’s dark-horse pick, the Denver Broncos, proved that on their day, they can beat anyone - even the league’s best.
The Eagles capitulated in the second half, scoring only seven points after the break, allowing the visitors to score 18 unanswered points in the fourth quarter.

Buffalo Bills (4-1)
A tightly fought AFC East Week 5 showdown against the New England Patriots ended with a game-winning field goal for the Patriots in the closing moments of the fourth quarter.
Patriots' receiver Stefon Diggs returned to haunt his former team, producing a 12-catch, 146-yard performance to help end the Bills' four-game unbeaten run.
