Updated Sunday night, Sept. 27: NFL Week 3's late afternoon windows are final. NBC's Rams at Broncos Sunday Night Football was still live with Los Angeles ahead 13-0 near the end of the first half.

In Rio de Janeiro, Baltimore beat Dallas 34-31 on Tyler Loop's 56-yard field goal as time expired. NBC Sports reports Lamar Jackson hit Zay Flowers for 27 yards to set up the kick after Brandon Aubrey's 23-yarder had tied the game with seven seconds left. The Ravens moved to 2-1; the Cowboys fell to 1-2. Derrick Henry ran for two scores; Dak Prescott threw for 276 yards in the loss.

Las Vegas rallied from a 27-16 third-quarter deficit to beat New Orleans 35-27 and improve to 3-0. NBC Sports credits four fourth-quarter takeaways and Kirk Cousins' three touchdown passes, including scoring throws to Cody White and Brock Bowers in Bowers' 2026 debut (10 catches, 116 yards). The Saints dropped to 1-2.

San Francisco held off Arizona 36-30 to stay unbeaten at 3-0. Yahoo Sports reports Brock Purdy threw four touchdown passes and George Kittle caught two scores even after Mike Evans (ribs) and Trent Williams (stinger) left and did not return. Christian McCaffrey added 116 yards from scrimmage and a touchdown.

Earlier Sunday finals already on the board include Detroit 31-24 over the Jets, Kansas City 24-10 at Miami, Washington 33-31 over Seattle, plus the early-window bank (Bills, Browns, Colts, Giants, Steelers, Jaguars). Those earlier finals were already on the Week 3 board before the late windows closed.

Where to watch: Rams-Broncos continues on NBC and the NFL app; live blogs at CBS Sports track in-game scoring. Full Week 3 boxes remain on NFL.com and network scoreboards.

NBC Sports and Yahoo agree on the late-window finals listed above. They still differ on injury fallout weight — Evans/Williams for San Francisco, and Dallas's late officiating arguments on the Flowers play — until Monday injury reports and league pool reports settle. Rams-Broncos remained in progress on the CBS Sports live blog at last check.
