Watching from the cozy indoors at field level was Peyton Manning as Brock Osweiler and the Broncos (9-2) overcame a 21-7 fourth-quarter deficit and handed the Patriots (10-1) their first loss since 2014. [...] the Carolina Panthers (11-0) are the NFL’s only remaining unbeaten team. Osweiler threw a 3-yard touchdown pass to Bubba Caldwell with 1:09 left in regulation to put the Broncos up 24-21. Brady, playing without injured tight end Rob Gronkowski, needed just five plays to drive the Patriots 51 yards and into range for Stephen Gostkowski’s 47-yard field goal that tied it at the end of regulation. New England won the coin toss and elected to receive, but thanks to a sack by Von Miller, Denver forced a three-and-out. Overall, the Broncos ran for 179 yards, particularly impressive given their two-touchdown deficit for much of the first half and the 21-7 hole in which they found themselves after Brady threw a 63-yard scoring pass to Brandon Bolden on the first play of the fourth quarter.
