The Sunday afternoon slate for Week 9 is headlined by two big AFC matchups with playoff implications. In the early afternoon window, it's two first-place teams facing off when the Indianapolis Colts (7-1) head to Pittsburgh (4-3) for a showdown with the Steelers.

While keeping a positive game script, the Bills out-physicaled the Chiefs and won the line of scrimmage. Running back James Cook went over 100 yards, and establishing that helped Bills quarterback Josh Allen gash the Chiefs defense on another of its weak points this season: play action.

Week 7 in the NFL had 12 games on Sunday, starting and ending with the NFC West. It started with the final London game of the year with the LA Rams blowing out the Jacksonville Jaguars. It ended with the San Francisco 49ers beating the Atlanta Falcons on Sunday Night Football.

With a successful extra point attempt from Brandon Aubrey, Denver leads 44-17 with 7:14 in the fourth quarter. The Dallas Cowboys can't catch a break, as Dak Prescott throws his second interception of the game straight into the arms of second-year linebacker Dondrea Tillman, who returns it for 38 yards.
