Colts Strike First in London as Unbeatens Collide in Week 4 Late Window

The Indianapolis Colts opened NFL Week 4 on Sunday, 4 October 2026, with a 30-13 win in the London game, clearing the stage for a late slate headlined by unbeaten against unbeaten in Las Vegas.

Chicago and Green Bay also banked wins in the early window. The Bears and Packers both took care of business before most West Coast fans had settled in, according to live coverage from The Guardian.

The main event is Las Vegas. The Raiders are 3-0 at home against the 3-0 Kansas City Chiefs. Kickoff is set for 4:25 p.m. ET on CBS, per Yahoo Sports.

Kansas City arrives with numbers to back up the hype. The Chiefs averaged 29.3 points per game, seventh in the league, and 416.3 yards per game, second in the league, ahead of kickoff. Oddsmakers listed them as -225 favorites against Las Vegas, which simply means they are expected to win outright, per NFL.com.

The other late CBS window is just as heavy. The 2-1 Denver Broncos travel to face the 3-0 San Francisco 49ers in San Francisco, also at 4:25 p.m. ET. San Francisco has protected home field so far, while Denver is trying to prove its 2-1 start can hold up against a complete roster.

Miami and Los Angeles face longer climbs. The 0-3 Dolphins draw the 3-0 Minnesota Vikings. The 0-3 Chargers go on the road to Seattle to play the 2-1 Seahawks.

What makes this stand out is the calendar. Four weeks in, records start to mean something. A 3-0 team that moves to 4-0 gets breathing room and tiebreakers that matter in January. An 0-3 team staring at 0-4 faces a different kind of math.

For fans, this means appointment viewing in the late window. Two games with unbeaten teams, plus a pair of winless teams fighting to save their seasons. Food on the stove, four games stacked deep. That is fall Sunday football.
