Answer based on context:

In their first road game of the season, the Broncos traveled to Orchard Park, New York to face the Buffalo Bills. After a 38-yard field goal by Broncos' placekicker Brandon McManus gave the Broncos the lead late in the first quarter, the Bills grabbed the lead, with a 2-yard touchdown from quarterback Tyrod Taylor to wide receiver Andre Holmes on a deflected pass. The Broncos responded, when running back Jamaal Charles eluded Bills' defenders for a 12-yard touchdown &#8212; Charles' first touchdown as a Bronco. The Broncos were attempting to add to their lead on their next possession, however, a 44-yard pass completion from quarterback Trevor Siemian to wide receiver Emmanuel Sanders was overturned by a Bills' challenge, as replay indicated that Sanders did not maintain full control of the football at the Bills' 44-yard line as cornerback Tre'Davious White knocked the ball out. McManus and Bills' placekicker Steven Hauschka proceeded to alternate field goals, with a 28-yarder by McManus giving the Broncos a 16-13 lead midway through the third quarter. However, the Broncos were held scoreless for the remainder of the game, and the Bills took the lead for good, with Taylor connecting with tight end Charles Clay on a 6-yard touchdown pass. A 53-yard field goal by Hauschka extended the Bills' lead to 23-16 early in the fourth quarter. The Broncos drove to as far as the Bills' 24-yard line on their first possession of the fourth quarter, however, Siemian was intercepted by White. Five plays later, the Broncos' defense forced an incomplete pass off Taylor at the Broncos' 46-yard line, hoping to receive the football back after a punt. However, linebacker Von Miller was flagged for an unsportsmanlike conduct penalty in which he offered to help Taylor off the turf, then pulled his hand back. After the Bills earned three first downs and forced the Broncos to use all of their team timeouts, Hauschka added a 27-yard field goal with 3:18 remaining in the game. The Broncos had one last offensive possession, but did not advance past the Bills' 42-yard line. Prior to this game, 32 Broncos' players decided to kneel during "The Star-Spangled Banner" after President Donald Trump made comments about the national anthem protests two days prior.
