Q: Passage: Coming off their win over the Giants, the Broncos returned home for an AFC West duel with the Oakland Raiders on Monday Night Football. The Broncos jumped out to a 17-0 lead, with a two-yard touchdown pass from quarterback Peyton Manning to wide receiver Eric Decker, a 53-yard field goal by placekicker Matt Prater and 12-yard touchdown pass from Manning to wide receiver Wes Welker, the latter of which occurred in the second quarter. The Raiders got on the scoreboard when quarterback Terrelle Pryor completed a 73-yard touchdown pass to wide receiver Denarius Moore. The Broncos subsequently added to their lead, with Manning throwing a 13-yard touchdown pass to tight end Julius Thomas, followed by two field goals by Prater a 41-yarder just before halftime and a 40-yarder midway through the third quarter. Following a Manning fumble, the Raiders narrowed the Broncos' lead, with Pryor tossing the football on a running play to running back Darren McFadden, and McFadden throwing a 16-yard touchdown pass to fullback Marcel Reece, however, the Broncos responded early in the fourth quarter, with running back Ronnie Hillman rushing for a 1-yard touchdown. The Raiders scored a late touchdown, with McFadden rushing for a 1-yard touchdown, however, the Broncos recovered the ensuing onside kick, sealing the win. This was the 17th meeting on Monday Night Football between the Broncos and Raiders tied for the most frequent pairing in Monday Night Football history with the Dallas Cowboys & Washington Redskins, who will meet for a 17th time in 2015.
