Week 4 opens overseas. The Indianapolis Colts face the Washington Commanders at Tottenham Hotspur Stadium in London at 9:30 a.m. ET on Sunday, with the game on NFL Network and available on mobile via NFL+ per the league's how-to-watch guide.

The matchup is a cross-conference international window one week after the NFL's first regular-season game in Rio de Janeiro. For East Coast fans it is a morning kickoff; for West Coast viewers it is effectively a dawn start. The early slot clears the board for the full domestic slate that begins at 1 p.m. ET with Jets-Bears and seven other games.

London remains a recurring October stop for the league's international series. Tottenham's venue has hosted multiple NFL games in recent seasons, and the 9:30 a.m. ET time is the standard U.S. television window for those London openers. NFL.com lists it first on the Sunday board, ahead of the CBS and FOX afternoon packages and NBC's Sunday Night Football.

Backstory: International games give the league a global audience and force American fans onto an unusual clock. Roster travel, sleep, and practice timing matter more than in a normal Sunday home game — details teams manage all week before the trip across the Atlantic.

Where to watch: NFL Network and NFL+ mobile for the London game at 9:30 a.m. ET Sunday from Tottenham Hotspur Stadium.
