Niners defense scores twice in win over Saints

NEW ORLEANS (AP) — Colin Kaepernick ran for one score that he made look easy and threw for a touchdown in another performance

that validated coach Jim Harbaugh's decision to start him.

The San Francisco defense added its share of big plays and the 49ers ended the New Orleans Saints' three-game winning streak,

31-21 on Sunday.

Ahmad Brooks and Donte Whitner each returned interceptions for touchdowns and the 49ers sacked Brees five times.

Kaepernick was solid in his second career start while Alex Smith, deemed healthy enough to suit up after recovering from a

concussion, watched from the sideline. Kaepernick passed for 231 yards, including a short touchdown to Frank Gore. He also

ran for a 7-yard score. He threw his first career interception, but it was inconsequential.

Brees finished with 267 yards and three TDs. After rushing for 140 yards or more in each of its previous three games, New

Orleans (5-6) managed only 59 yards against San Francisco (8-2-1).

One of Brees' scoring passes went to Marques Colston, who set a Saints record with his 56th career touchdown with the club.

The Niners gained 144 yards on

the ground, led by Gore with 83. The Saints shut down tight end Vernon

Davis, the player they

feared perhaps the most, but the Niners' other tight end, Delanie

Walker, had three catches for 81 yards, including one for

45 yards to set up a touchdown.

San Francisco's interceptions came during a 21-0 spurt that turned a 14-7 deficit into a 28-14 lead.

Brooks snagged the first,

returning it 50 yards late in the first half. The second came on Brees'

first pass of the second

half. The ball deflected off Colston's hands as the leaping

receiver was upended and briefly shaken up. Whitner snagged the

deflected pass and returned it 42 yards to make it 28-14

Brooks, Aldon Smith and Justin Smith each had 1½ sacks, all in the second half.

Since losing to the New York Giants on Oct. 14, the Niners are 5-0-1 and now hold a 2 1/2-game lead in the NFC West with five

games to go.

It seems their biggest problem at this point is deciding who should be their No. 1 QB. Smith, who led the Niners to the NFC

title game last season, started the first nine games this season before his injury.

The Saints, meanwhile, missed a chance to pull into a tie for the last NFC wild card berth, and remain a game out with another

tough game coming up at Atlanta on Thursday night.

Kaepernick used the running ability that served him so well in college at Nevada to give the Niners the early lead, scoring

on a read-option run that fooled the Saints defense as well as the Superdome crowd, which erupted, initially believing the

play had been snuffed out, while Kaepernick scampered to his left and scored easily.

The drive was highlighted by Mario Manningham's 40-yard gain after Kaepernick found him wide open on a short crossing route.

Then, New Orleans' offense, which could not muster a first down on its first two drives, suddenly ignited, marching 79 yards

in 10 plays — highlighted by Joe Morgan's diving 33-yard catch — to tie it on tight end David Thomas' 6-yard catch.

San Francisco entered the game

allowing a league-low 13.4 points per game. The Saints surpassed that in

the second quarter

when Brees hit Colston to make it 14-7 and capitalize on Ted Ginn

Jr.'s fumbled punt, which Rafael Bush had recovered on the

49ers 10.

New Orleans looking intent on

going up by two scores after Kaepernick's first career interception on

an underthrown pass that

cornerback Patrick Robinson easily caught. But the crowd has

hardly finished celebrating when Brooks stepped in front of Brees'

pass for Jimmy Graham and returned it 50 yards to tie it at 14

shortly before halftime.
