Unbeaten NFL teams face tough tests in week four as division rivals clash and dramatic finishes shake up the season standings.
Only three teams remain with a 100% record in the National Football League after two more perfect starts were halted during an action-packed week four of the season, which began with the Indianapolis Colts defeating the Washington Commanders in London.
Division rivals met as the Kansas City Chiefs and Las Vegas Raiders put their undefeated runs on the line, while the San Francisco 49ers and Minnesota Vikings marched on to improve their records to four wins and zero losses, according to information published by BBC.
Across the league, dramatic road victories, standout performances from star quarterbacks, and mounting injury concerns shaped a pivotal Sunday slate that heavily impacted the early Super Bowl contention picture.
Kansas City Chiefs hold off Las Vegas Raiders
The Kansas City Chiefs extended their dominance over the Las Vegas Raiders, though the visitors pushed the defending contenders all the way before falling 30-27 in a game featuring three fourth-quarter lead changes.
New running back Kenneth Walker powered the Kansas City Chiefs with two touchdowns in just nineteen seconds, finishing the matchup with 177 rushing yards from 22 carries to keep his team firmly in championship contention.
Despite a late scoring strike from Brock Bowers and solid efforts from Kirk Cousins, the Las Vegas Raiders fell just short as a final-play pass was intercepted, leaving Kansas City at the top of the division.
San Francisco 49ers and Minnesota Vikings stay perfect
The San Francisco 49ers secured a hard-fought 24-14 victory over the Denver Broncos, anchored by a crucial fourth-quarter touchdown catch and run from tight end George Kittle to seal the contest.
Quarterback Brock Purdy maintained his efficient start, leading the league in touchdown passes while avoiding interceptions and sacks through the first four games of the 2025 campaign.
Meanwhile, the Minnesota Vikings emerged as the season's biggest surprise at four and zero, grinding out a 15-10 win against the Miami Dolphins as kicker Will Reichard successfully converted five field goals.
New England Patriots stun Buffalo Bills
Quarterback Drake Maye bounced back from a difficult outing to lead the New England Patriots to a dramatic 29-26 road victory against the formidable Buffalo Bills and MVP Josh Allen.
Trailing late in the game, Drake Maye connected with Efton Chism for a spectacular one-handed touchdown catch in the endzone, capping off a 269-yard passing performance.
The victory halts any doubts about the young signal-caller, proving that the New England Patriots remain a dangerous squad after nearly reaching the Super Bowl last season.
Los Angeles Rams edge Philadelphia Eagles
The Los Angeles Rams rallied from a ten-point halftime deficit to defeat the Philadelphia Eagles 24-21, as running back Kyren Williams punched in two late touchdowns.
Receiver Puka Nacua contributed 125 receiving yards and a touchdown for the Los Angeles Rams, while the Philadelphia Eagles suffered major injury blows ahead of their upcoming London trip.
Star running back Saquon Barkley exited early with a hamstring injury, adding to roster concerns that already included sidelined wide receiver DeVonta Smith and tight end Dallas Goedert.
