Brooks and Whitner returned interceptions for touchdowns, the 49ers sacked Drew Brees five times, and San Francisco ended the New Orleans Saints’ three-game winning streak, 31-21 on Sunday.

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.
Brees finished with 267 yards and three TDs. After rushing for 140 yards or more in each of its previous three games, New Orleans managed only 59 yards against San Francisco.
One of Brees’ scoring passes went to Marques Colston, who set a Saints record with his 56th career touchdown.
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 turned a 14-7 deficit into a 28-14 lead.
