The Chiefs play next on Sunday, November 23, 2025, at 4:25 p.m. Eastern, when Kansas City hosts the Indianapolis Colts at Arrowhead Stadium in a Week 12 game. That kickoff is one of five Sunday afternoon windows the NFL can assign, and the time slot itself is the product of a scheduling system most fans never see.

Every week, the NFL tells 32 clubs when they play next, and almost every part of that answer — the day, the hour, the network — is governed by broadcast contracts and competitive-balance rules. This explainer unpacks the mechanism behind the schedule, the numbers that constrain it, the edge cases that flip kickoff times, and the practical steps that give you the most reliable answer. The league has already announced dates through Week 18, with only kickoff times in Weeks 17 and 18 subject to flexible scheduling.

The scheduling system behind the next kickoff

The NFL does not schedule games one week at a time. It releases the full 18-week regular-season schedule in May, roughly four months before Week 1, after a process that starts with each team submitting stadium availability and other constraints. Because Arrowhead Stadium is also a concert and event venue, Kansas City's home dates are blocked out alongside the club's requests, and the league works around those windows.

Each game is then assigned a broadcast partner: CBS for the Sunday afternoon AFC package, Fox for the Sunday afternoon NFC package, NBC for Sunday Night Football, ESPN for Monday Night Football, and Amazon for Thursday Night Football, with a rotating footprint of streaming and cable partners. Because most Chiefs games involve two AFC teams, they fall under CBS's Sunday afternoon window — which in the current contract means an early (12:00 or 12:30 p.m.) or late (3:05 or 3:25 p.m.) slot.

The league's scheduling department, working with the networks, then balances two things: competitive fairness and television audience. The formula favors star quarterbacks and marquee markets in the afternoon and prime-time windows, because each of those windows reaches tens of millions of households. That is the why beneath "when do the Chiefs play next" — the Chiefs are arguably the league's most valuable television property, so their games are frequently placed late in the afternoon or in prime time.

The counterintuitive detail: the published schedule is a contract, not a prediction. The NFL can move any game inside Weeks 5 through 17 to a later window as long as the change is announced a set number of days before kickoff. The date stays; the hour changes.

The numbers that constrain the answer

The contract windows set the schedule's edges. Sunday afternoon games occupy one of roughly five windows — early Sunday (12:00 noon or 12:30 p.m. Eastern), late Sunday (3:05 or 3:25 p.m. Eastern), and the prime-time packages — Sunday night at 8:20 p.m. Eastern, Monday night at 8:15 p.m. Eastern, and Thursday night at 8:15 p.m. Eastern.

Each window has a different advertising audience. Sunday afternoon windows reach roughly 10 to 25 million average viewers, Sunday night around 18 to 20 million, and the Super Bowl well over 100 million. Those numbers are why networks protect their prime windows with rule-built guards.

The flex-scheduling rules have exact numbers. From Week 5 onward, the NFL can move a Sunday afternoon game to Sunday night with 12 days of notice. During the last four weeks, the notice window shortens to 6 days, and no more than 3 games can be flexed on a 6-day decision. Thursday night flexes require 28 days of notice. A club that already has 5 prime-time games cannot be flexed into a sixth.

From Week 12 on, the Sunday night window is protected at the top: no more than 3 Sunday-night flexes per season, and a Sunday afternoon game can be flipped into the 8:20 p.m. slot only if the league announces it by Tuesday. The current link between Kansas City and the Colts was already announced in the May release, so barring an injury-driven shift, the 4:25 p.m. time is the week's plan.

Edge cases that move the kickoff

The most reliable edge case is a Thursday game pulling forward. If the Chiefs play on a Thursday night, the answer to "when do they play next" is a day 3 days after their previous game, not the usual 7. The buildup week is compressed because the league protects Thursday-night inventory with 28-day notice.

Another is a Saturday slot in December. When the college football season ends, the NFL moves late-December games to Saturdays, usually in Weeks 15 and 16, and the league announces the exact slots by November. A Kansas City game landing on a Saturday in December usually stays on that Saturday for national television, but the kickoff hour (often 1:00 or 4:25 p.m. Eastern) moves with the network.

The most common mover is a flex. If the Chiefs' Week 13 opponent is a playoff contender and the Sunday-night window is weak, the league can shift the game to prime time with 12 days of notice. Ask the league to protect the 10-day window, and the date you marked may move.

A red-flag checklist helps you separate a firm date from a provisional one:

Any game in Weeks 5-17 can change its kickoff hour until 12 days out (6 days in Weeks 14-17). A Thursday-night game cannot flex closer than 28 days out. Week 18 kickoff times are set after Week 17 results, usually within days. A team with 5 or more prime-time games cannot be flexed into another. The Sunday-night window caps at 3 flexes per season, so not every candidate moves.

Common misconceptions

The first misconception is that the published schedule is final. It is only final in date, not time. The NFL reserves the right to move games between Sunday afternoon and Sunday night, and between Thursday night and Sunday, inside the notice windows. A "TBD" next to a kickoff is not a mistake; it is the league holding a slot it may fill later.

The second is that the Chiefs always play Sunday at 4:25. They often do, but not always. Kansas City opens seasons on Thursday night when it hosts the league's kickoff game, and it appears on Monday night and Sunday night throughout the fall. The 4:25 p.m. slot is a favorite, not a guarantee.

The third is that "next" means this week. If the Chiefs just finished a Thursday game, their next game is in 10 days, not 7, and the compressed turnaround changes the answer to the question. Similarly, during a bye week the answer is a date 14 days after the last game.

The fourth is that a weather forecast changes the kickoff. It does not, in the regular season. The league adjusts only for severe safety conditions, and the NFL has generally held kickoff times even in extreme heat and cold.

Practical steps to confirm the next game

The most reliable first step is the official league schedule page, which lists each game's date, time, network, and venue, and flags changes. The Kansas City club site mirrors it, and its schedule page carries the same feed. Neither source sells tickets or advertises heavily, so they are the cleanest way to confirm the next kickoff.

The second step is to check the broadcast listing on your local provider, because the network — CBS, Fox, NBC, ESPN or Amazon — tells you which window the game is in, and the listed start time confirms the exact slot. Local listings are refreshed as soon as the league announces a flex.

The third step is a calendar reminder that repeats weekly and excludes the bye. Set the reminder for the Monday before the game, so a 12-day or 6-day flex notice arrives before you travel or plan a watch party. A good reminder includes the venue and the time zone, since a 4:25 p.m. Eastern game is 3:25 p.m. in Kansas City.

The fourth step is to verify in the 48 hours before kickoff, because a flex can move a Sunday afternoon game to Sunday night with 6 days of notice in December. A final check on the league site or the club's social feed takes about 30 seconds and covers the last-minute changes.

A comparison of the windows helps you plan around the most likely slot:

Window Typical kickoff (Eastern) Notice before a change Who carries it
Sunday early 12:00 or 12:30 p.m. Flex eligible after Week 5 CBS or Fox
Sunday late 3:05 or 3:25 p.m. Flex eligible; 12 days, 6 in Weeks 14-17 CBS or Fox
Sunday night 8:20 p.m. 12 days; 6 days in final four weeks NBC
Monday night 8:15 p.m. Announced with schedule; rarely changed ESPN
Thursday night 8:15 p.m. 28 days before a change Amazon

A timeline of a typical season shows when the answer changes:

When What changes Effect on "next game"
May Full schedule released Date fixed; time provisional
Week 5 Flex window opens Sunday afternoon can move to Sunday night
Week 12 Late-season protection begins Sunday-night changes need Tuesday notice
Weeks 14-17 6-day flex window A game can move with under a week's notice
Week 18 Kickoff times set late Date fixed; time announced after Week 17
48 hours before kickoff Final check Confirms time, network, venue

Limits of any advance answer

The schedule's forward-looking answer is only as good as the notice rules allow. Weeks 1 through 4 are locked and rarely change. Weeks 5 through 12 are stable in date but can shift in hour. Weeks 13 through 17 are the least certain, because the 6-day flex window in the final four weeks lets the league move games with barely more than one business day of notice.

The mechanics also do not predict injury-driven changes. If a star quarterback is ruled out, the league does not move the kickoff; the game stays in its slot. What changes is the broadcast assignment, which the network can switch, not the time.

One more caveat: the schedule you see on a search result may be cached. A streaming service's listing, a ticketing site, or a fantasy app may lag the league's own announcement by hours, and the lag is worst during a flex week. The official league and club pages are the only sources refreshed at the moment of the change.

The article is general educational information about how the NFL schedule works, not a game-time guarantee, a betting recommendation, or a prediction of outcomes. Verify the kickoff with the league, the club, or your local broadcaster before making travel or viewing plans, and consult a qualified local professional for any consequential decision.
