A six-game NFL Sunday? On four different channels?

From the crack of dawn to well past last call at “Bob’s Burgers,” Week 4 of the NFL in L.A. is, from all estimations, unprecedented excess.

“I’ll bet there has probably never been a Sunday in NFL history when the fans of one city had access to six games,” said Mike Mulvihill, Fox’s executive vice president of research and strategy.

Factor in the games Thursday and Monday nights, and the eight total games involving 16 teams means we’ll see half the entire NFL on display.

Mulvihill explained that there are four Sundays this season when a network that usually has a single Sunday game will get two games in L.A. because of how the Rams and Chargers sometimes get painted into scheduling corners.

“It’s challenging over the course of the season, but it works out fairly,” Mulvihill said. “In the end, it’s good for both networks because they all count toward national ratings, and it’s good for the fans to have access to that many games.”

This rare Sunday begins with CBS hanging onto its scheduled doubleheader, but it gets muddled because Fox also doubles up with both L.A. teams playing in different windows.

Make that, triples up, because of another game in London that will go to everyone.

What also adds to the confluence is that the second Fox game (Chargers-Eagles) will kick over to L.A. sister station KCOP, because the NFL is contractual obligated to show every minute of each L.A. team’s game to the home market. They can’t chance an overtime Rams game spilling into the Chargers’ kickoff slot.

This is how it plays out:

Pre-dawn

New Orleans vs. Miami from Wembley Stadium in London, 6:30 a.m., Channel 11 (Kevin Burkhardt, Charles Davis)

Early window

Rams at Dallas, 10 a.m., Channel 11, (Chris Myers, Daryl Johnston). It blots out Fox’s coverage of Detroit-Minnesota and Carolina-New England (Joe Buck, Troy Aikman).

Pittsburgh at Baltimore, 10 a.m., Channel 2 (Ian Eagle, Dan Fouts). CBS picked this one instead of Buffalo-Atlanta, Tennessee-Houston, Cincinnati-Cleveland and Jacksonville-N.Y. Jets.

Late window

Philadelphia at Chargers, 1:05 p.m., Channel 13, (Dick Stockton, Mark Schlereth). The MyTV affiliate, which is Fox’s local spill-over channel, lands this. Fox’s other games in this window that are off limits: N.Y. Giants-Tampa Bay and San Francisco-Arizona.

Oakland at Denver, 1:25 p.m., Channel 2. (Jim Nantz, Tony Romo). The only CBS late game. And it’ll be our second Nantz-Romo game of the weekend (see below). The Raiders will, of course, crush the Chargers in the L.A. market going head-to-head on TV, but Fox will have to live with that.

Prime-time window

Indianapolis at Seattle, 5:20 p.m., Channel 4 (Al Michaels, Cris Collinsworth, Michele Tafoya)
