In danger of losing three straight for the first time in four seasons, the Denver Broncos face their former coach without their future Hall-of-Famer under center.
With Peyton Manning sidelined, Brock Osweiler makes his first career start Sunday when the visiting Broncos face John Fox's improving Chicago Bears.
A season that looked promising has become concerning for Denver, which followed a 7-0 start by dropping two straight for the first time since September 2012 - the season after the Broncos last lost three in a row.
They'll try to avoid doing it again without Manning, who was benched last Sunday after throwing four interceptions in a 29-13 loss to Kansas City.
