Broncos 34, Browns 12

DENVER -- Peyton Manning threw three touchdown passes, including two to Eric Decker, and the Denver Broncos kept rolling by beating the Cleveland Browns 34-12 Sunday for their 10th consecutive victory.

The Broncos (12-3) matched the second longest win streak in team history -- they also won 10 in a row in 1984. They can wrap up the No. 2 playoff seed and first-round bye that goes with it with a win at home over Kansas City in a regular-season finale next Sunday. Denver also could move up to the top seed with a win in the finale and a Texas loss.

Manning finished with 339 yards passing, completing 30 of 43 passes with an interception. He had his 77th career game with at least three touchdown passes, tying Brett Favre for most such games in NFL history.

It was the 10th time this season that the Broncos have scored 30 or more points in a game, and the eighth time during the streak. That tied them with New England for most 30-plus points game in the NFL this season and also matched the club mark, achieved in 1998 and 2000.

Denver's defense kept the Browns (5-10) out of the end zone until midway through the fourth quarter. Cleveland lost its quarterback, Brandon Weeden, to a right shoulder injury late in the third quarter when he was taken down for a sack by Von Miller. Weeden finished 12 of 19 for 104 yards. Colt McCoy came on to finish the game at quarterback for the Browns.

Miller increased his season sack total to a team-record 17.5, surpassing the previous high of 17 by teammate Elvis Dumervil in 2009. Denver had six sacks in the game.

Trailing by 11 at the half, the Browns managed to get within 14-6 on Phil Dawson's second field goal, a 53-yarder with 11:09 remaining in the third quarter.

But the Broncos ran off the next 17 points, starting with Manning's second touchdown pass to Decker, which covered eight yards. Decker celebrated the score by rolling the football into the end zone fence as if he were pitching a bowling ball down the alley.

Matt Prater added a 27-yard field goal, and Jacob Hester ran for a 1-yard touchdown, a score set up by Joshua Cribbs muffed punt that was recovered by Denver's Lance Ball at the Browns' 19-yard line.

Cleveland finally scored a touchdown when McCoy passed six yards to Greg Little with 7:56 remaining but it was too little, too late.

The Broncos led 14-3 at halftime, missing a chance to go up even more when safety Usama Young made a diving interception of a Manning pass in the end zone with just seconds remaining in the second quarter. Manning had been trying to get the ball to Knowshon Moreno.

Young's interception survived a replay review, unlike the apparent pick and long return by Broncos safety Rahim Moore earlier in the game after it was determined the ball had hit the ground before he got up and ran with it.

The Broncos gained command from the outset with Manning finishing off a pair of 80-yard drives with touchdown passes, the first coming at the end of Denver's opening series.

Manning hit Demaryius Thomas in stride from 22 yards out, putting the ball into his outstretched hands as cornerback Sheldon Brown battled him, unable to dislodge it.

Weeden answered with a drive by the Browns that reached Denver's 8-yard, but on a third-and-goal play, safety Mike Adams, a former Brown, tipped away a pass in the end zone intended for Josh Cooper. Dawson came on to kick a 27-yard field goal for the Browns.

Manning put together another long drive by the Broncos leading to a 10-yard scoring pass to Decker, who outfought Brown in the end zone for the ball.

Brown left the game later in the second quarter with a head injury and did not return.
