Manning tosses 3 TDs as Broncos rout Raiders

Last season, the questions were about his right arm.

A year later, the questions are about how many records his right arm will set.

Peyton Manning tossed three more touchdown passes in the Denver Broncos' 37-21 win over the Oakland Raiders.

The 37-year-old Manning has the most NFL touchdown passes through the first three games of an NFL season with 12. He's yet to throw an interception.

He's also led his Broncos to 14 straight regular-season wins, tying the franchise mark set in 1998 when John Elway's-led Denver squad won its first 14 games.

After becoming the first signal caller in 51 years and sixth overall to throw seven TD passes in a game in Denver's opener against the Baltimore Ravens, Manning fired two more touchdowns against the New York Giants in Week 2.

Manning, who was 21-of-24 for 264 yards and three scores in the first half, finished 32-of-37 for 374 yards for Denver (3-0), which has outscored its opponents 127-71 this season.

"When we're executing and not making mistakes, we can go the distance. We can go 80 yards, take advantage of a short field," Manning said.

Eric Decker caught eight passes for 133 yards and a touchdown, while Wes Welker hauled in seven receptions for 84 yards and a score in the triumph.

Things aren't all rosy for the Broncos, though. All-Pro left tackle Ryan Clady was put on season-ending reserve Wednesday after suffering a Lisfranc foot injury in the win over the Big Blue. Chris Clark started in Clady's place at left tackle.

Off the field, already suspended linebacker Von Miller continues to give the organization a bit of a black eye as news broke that the All-Pro allegedly collaborated with a sample collector in an attempt to beat an NFL drug test.

Miller was initially fighting a four-game suspension this summer for violations of the league's substance-abuse policy, but speculation began to circulate that the NFL was attempting to lengthen the penalty to as much as a year -- apparently because of the alleged tampering. The NFL did increase the ban from four to six games.

Terrelle Pryor, who suffered a concussion after taking a helmet-to-helmet hit by Broncos linebacker Wesley Woodyard late in the game, completed 19-of-28 passes for 281 yards and a touchdown for Oakland (1-2), which was coming off a win against the Jacksonville Jaguars in Week 2.

"I have no idea," Raiders head coach Dennis Allen said of Pryor's availability for Oakland's upcoming game Sunday against the Washington Redskins. "He's got to go through the protocol, just like everybody else."

The Broncos, who jumped out to a 17-0 second-quarter lead, were up 10-0 before the Raiders even picked up a first down.

After Oakland punted to start the game, Manning capped an 8-play, 55-yard march with a 2-yard TD pass to Decker. Matt Prater booted through a 53- yard field goal late in the first and Manning flipped a 12-yard TD pass to Welker midway through the second for Denver's 17-point margin.

Denarius Moore broke free from a pair of Denver tacklers following a deep comeback route and raced 73 yards for a score to get Oakland on the board midway through the second, but Manning had a quick answer.

Decker broke free for a 61-yard gain down the right sideline on the first play of the Broncos' ensuing series and Manning found Julius Thomas for a 13-yard touchdown three plays later for a 24-7 Broncos margin with 3:40 left in the half.

Denver then forced another Oakland three-and-out and Prater booted through a 41-yard field goal with 19 ticks left until intermission to give the Broncos a healthy 27-7 cushion heading into the break.

Prater split the uprights from 40 yards out to increase the margin to 30-7 midway through the third.

Darren McFadden floated a 16-yard TD pass to Marcel Reese late in the third to get Oakland within 30-14.

Ronnie Hillman sprinted in from a yard out early in the fourth for Denver and McFadden crossed the goal line from a yard out later in the stanza to cap the scoring.
