Answer based on context:

The Packers flew to Denver for a duel with Peyton Manning and the undefeated Denver Broncos. The Broncos wore their alternate blue uniforms with white pants as worn in Super Bowl XXXII. Packers cornerbacks Sam Shields and rookie cornerback Quinten Rollins suffered a shoulder injury in the game and their returns were questionable. The Broncos took the lead early in the first quarter when Ronnie Hillman scored a 1-yard touchdown. In the second quarter, Hillman scored another touchdown and the Broncos led 14-0. The Broncos lead became 17-0 when Brandon McManus made a 50-yard field goal. Von Miller was injured during the second quarter. The Packers struck back when Eddie Lacy scored on a 2-yard touchdown run. They trailed 7-17 at halftime. In the third quarter, the Packers cut Denver's lead to seven when Mason Crosby made a 56-yard field goal. Denver extended their lead to 24-10 when C.J. Anderson made a 28-yard run. Denver continued to dominate when Brandon McManus made a 24-yard field goal and DeMarcus Ware sacked Aaron Rodgers for a safety, making the score 10-29. The Packers defense finally recorded an interception when Damarious Randall picked off Peyton Manning. In this game, the Broncos held Rodgers to 77 yards passing, the lowest of his starting career in a game where he hasn't came off with injury.
